Chapter 49 Equipment Arrival and Temperature Control System Commissioning

Juan and Luis stood at the edge of the pit.

Watching the excavator dig soil shovel by shovel.

Emma came out of the main house and walked to Su Chen's side.

"The equipment supplier called."

"The refrigeration unit, air ducts, sensors, and control cabinet will be delivered this afternoon."

Su Chen glanced at his watch.

"Have them drive directly to the cold chain construction site, the workers unload the goods, and you check the model number."

At 2 p.m., a flatbed truck drove into the ranch.

Old Jack registered the vehicle information at the entrance and let it pass directly.

The truck was parked next to the cold chain construction site.

The driver got out of the car and took out the delivery slip.

Emma took the list and checked each item one by one.

One refrigeration unit, model medium frequency inverter, power 15 kilowatts.

There are four evaporators, each with a cooling capacity of five kilowatts.

Two condensers, along with a matching unit.

There are twelve temperature sensors and four humidity sensors.

One control cabinet, equipped with a touch screen and a remote communication module.

Air ducts, insulation pipes, refrigerant, copper pipes.

Various auxiliary materials.

Emma checked the documents and signed the delivery note.

Workers began unloading the goods.

Large equipment units are handled with forklifts, while small items are moved by hand.

All the equipment was neatly stacked on the open ground next to the construction site and covered with a tarpaulin.

The equipment installation technician got out of the driver's seat.

He was in his thirties, wearing work clothes and carrying a toolbox.

He walked up to Su Chen.

"Mr. Su, I'm Zhou, and I'm in charge of installation and debugging. Let me take a look at the site first."

Su Chen took him to the construction site.

Mike was at the edge of the pit, directing the workers to dig the foundation.

Master Zhou looked at the location of the foundation pit.

Then I checked the orientation of the equipment room.

"The equipment room is placed in the southwest corner of the cold chain, so that the heat dissipation surface of the unit faces outwards, which does not affect the insulation of the cold storage."

"The air ducts run through the wall from the equipment room into the refrigeration and freezing areas, and through the ceiling, without taking up floor space."

Su Chen asked, "Is the unit noisy when it's running?"

Master Zhou thought about it.

"The noise level of the medium-frequency inverter unit is not high, about 60 decibels, which is equivalent to the volume of normal conversation."

"But in order not to affect the cattle, the machine can be oriented to the west so that the noise can be dispersed outside the pasture."

Su Chen nodded.

"Do as you say."

The foundation pit has been dug.

Mike led the workers to lay a layer of crushed stone and compact it with a plate vibratory mixer.

"The gravel was laid 20 centimeters thick, and after it was compacted, the surface was flat and firm."

Next, the concrete foundation layer is poured, and the mixer is used to mix the materials on site.

Workers used wheelbarrows to transport the concrete to the edge of the pit and poured it in.

Use a vibratory stick to compact and smooth it out.

Emma stayed by the side, recording the construction progress and taking photos for future reference.

In the evening, the concrete foundation was poured and it was ready to solidify.

When Mike finished work, he said to Su Chen:

"Tomorrow we'll lay the insulation layer and steel mesh, and the day after tomorrow we'll pour the surface layer."

"The library installation will begin the day after tomorrow."

Su Chen nodded.

Master Zhou's equipment has been unpacked and inspected.

All parts are complete and ready for installation.

Su Chen returned to the main house, and Emma followed him in.

"Pierre's assistant sent an email asking if there's any progress on delivery capabilities."

Su Chen sat down.

"Reply to him that the cold chain is under construction and is expected to be completed in thirteen days."

"Once completed, the first delivery to Kalispel will commence immediately."

Emma replied with an email.

......

The next day, Mike brought the workers to the site early in the morning.

Extruded polystyrene boards were laid one by one on the concrete subbase.

Perfectly fitted.

Seal the seams with aluminum foil tape to prevent cold air from seeping in.

After the insulation layer is laid, a steel mesh is laid on top.

The reinforcing mesh is raised using spacers.

Ensure that the reinforcing bars are on top of the insulation layer and do not sink to the bottom when pouring concrete.

A concrete mixer truck drove into the pasture.

Concrete was poured directly onto the steel mesh.

Workers used a vibrator to compact the material and a long scraper to smooth it.

Once the surface is slightly dry, use a power trowel to smooth it.

The ground is now flat and smooth.

Mike stomped his foot on the ground.

"It's very tough; it can even handle heavy trucks without any problems."

Su Chen squatted down and looked at the ground.

It's flat and has no cracks.

The installation of the library has begun.

The workers first erected a steel frame.

Square steel pipes are welded into a frame and fixed to the concrete ground.

Polyurethane sandwich panels are embedded one by one into the frame.

The boards are joined together using tongue and groove joints.

Apply sealant to the gaps.

The warehouse walls were installed to a height of 2.5 meters.

The same material was used to cover the top.

The refrigerated and frozen sections are separated by an insulated panel.

A sliding door is installed in the middle, which can be opened in both directions.

The door frame is equipped with heating wires to prevent icing.

The buffer zone is located outside the cold storage area, with two doors that are linked together.

When the door is opened from the outside, it cannot be opened from the inside.

To prevent excessive leakage of cold air.

The equipment room was built with brick walls, separating it from the warehouse.

To prevent vibrations from the generator unit from being transmitted to the silo.

Master Zhou began installing the refrigeration equipment.

The refrigeration unit is fixed to the floor of the equipment room.

Copper pipes pass through the wall from the equipment room into the warehouse.

It is laid along the ceiling and connected to the evaporator.

The evaporators are installed on the ceiling of the refrigerator and freezer compartments.

The four corners are secured with shock-absorbing pads to prevent vibration.

Temperature sensors are placed in the cold storage area.

Avoid windy areas and doorways.

The sensor is connected to the control cabinet, and the data is uploaded in real time.

The control cabinet is installed in the equipment room.

The temperature and humidity at each point can be viewed on the touch screen.

Set the cooling parameters and check the equipment's operating status.

Master Zhou connected the power supply for the first power-on test.

The control panel lights up, displaying the current temperature inside the warehouse as 23 degrees Celsius.

Set the target temperature for the refrigeration compartment to 2 degrees Celsius and the freezer compartment to -18 degrees Celsius.

The compressor started, and a buzzing sound came from the equipment room.

The evaporator fan started spinning.

Cold air is blowing out of the air vent.

The temperature inside the warehouse began to drop.

Emma took out her phone.

Open the smart monitoring application provided by the equipment manufacturer.

Enter the device number and password to successfully connect to the control cabinet.

On the phone screen.

The real-time temperature of the refrigerated compartment is displayed at 22.3 degrees Celsius.

The freezer compartment is 22.1 degrees Celsius.

The data is refreshed every ten seconds.

Su Chen glanced at his phone.

I took another look at the control panel.

The data is consistent.

Master Zhou is conducting a simulated power outage test.

Turn off the power switch in the equipment room.

The control panel is black, and the compressor has stopped.

Three seconds later, the backup power supply automatically switched.

The control panel lit up again, and the compressor restarted.

Temperature data was not lost, and refrigeration continued.

Su Chen asked, "How long will the backup power last?"

Master Zhou said, "It's equipped with a 10 kWh battery pack, which can last for four hours at full load."

"If you just maintain a constant temperature and don't open and close the door frequently, it can last for more than eight hours."

Su Chen nodded.

We also tested the extreme low temperature mode.

Set the freezer compartment to -25 degrees Celsius.

The compressor is running at full speed.

The evaporator fan is running at high speed.

Two hours later, the temperature in the freezer compartment dropped to minus 25.3 degrees Celsius.

Meets the standard.

Su Chen requested that this temperature be maintained for two hours to test the stability of the equipment.

Two hours later, the equipment was operating normally.

No alarms, no malfunctions.

Master Zhou signed the debugging record book.

Write down "The equipment is operating normally and can be put into use".

Mike checked the airtightness of the vault.

All the gaps were filled with expanding foam.

Ensure there is no cold leakage.

Emma compiled the initial report on cold chain operations.

The equipment model, installation date, debugging data, and test results were recorded and archived.

John heard that the cold chain facility was almost finished, so he drove his pickup truck to visit the ranch.

Su Chen took him to see the cold chain construction site.

John walked into the cold storage area, touched the wall panel, and looked at the evaporator.

Then I went to the equipment room and looked at the generator set and control cabinet.

"Mr. Su, your cold chain business is quite large."

"In the future, not only will we use it, but the surrounding ranches can also use it."

Su Chen said, "Let's prioritize our own delivery service first, and we'll talk about the rest later."

John nodded and didn't bring it up again.

Anderson also arrived, standing at the entrance of the cold chain store and looking inside.

"Mr. Su, now that your cold chain is built and your delivery capacity is up, your beef can be sold to even more distant places."

"Could I use your delivery network for my regular cattle?"

"I'll pay for the shipping."

Su Chen said, "We can discuss it later. For now, we need to ensure the delivery of our own premium beef."

Anderson said nothing more and turned back.

Dazhuang was allowed to approach the cold chain construction site.

It slowly walked over and sniffed the outer wall of the equipment room.

He looked up at the evaporator's air outlet again and snorted.

Su Chen patted its head, signaling it to go back.

Black Fang patrols the perimeter of the construction area.

They chased away several wild rabbits that approached.

Lingfeng let out a cry from the sky.

Su Chen looked up.

Lingfeng hovered over the eastern side of the ranch, indicating that something was amiss.

Su Chen walked over and stood by the fence, looking into the distance.

An unfamiliar SUV was parked on the dirt road outside the ranch.

A person is taking pictures of the entire ranch with a camera.

Su Chen asked Old Jack to inquire.

Old Jack walked over and said a few words.

The man put away his camera and drove off.

Old Jack came back and said:

"He was a tourist who was passing by, saw that the ranch had nice scenery, took a few photos, and then left."

Su Chen did not pursue the matter further.

With the main cold chain infrastructure completed, the project has entered the sanitation and cleaning phase.

Emma purchased food-grade disinfectant.

Juan and Luis put on protective suits.

Wearing gloves, they used a sprayer to thoroughly disinfect the inside of the warehouse.

Walls, floors, ceilings, air vents, door frames.

Spray every corner.

After disinfection, ventilate for two hours.

Wipe again with clean water to remove any residue.

The veterinarian was originally there to perform hygiene checks.

He used cotton swabs to take several samples from the refrigerated area, the frozen area, and the buffer zone.

Put it in a sealed bag and take it back to the clinic for testing.

Two hours later, Ben called.

"The bacterial count meets the state's food storage standards and the food can be used."

Su Chen confirmed that the cold chain could be put into trial operation.

He had Juan bring several pieces of premium beef from the processing room.

Place it in the refrigerator compartment, set the temperature to two degrees, and close the door.

Emma stared at the temperature data on her phone.

There has been no fluctuation for 24 consecutive hours.

Su Chen stood at the entrance of the cold chain warehouse, looking at the tightly closed door.

Trial operation has begun.

If successful, the beef from Sunset Ranch will be able to leave Whitefish Town.

......

Su Chen convened a meeting of the ranch's core personnel in the main house's living room.

Emma, ​​veterinarian Ben, Juan, and Luis were all there.

Su Chen stood in front of the whiteboard.

Several keywords were written on it.

Slaughtering, pre-cooling, and cutting.

Packaging, cold chain, and distribution.

"Let's finalize the schedule today."

"From the moment the cattle enter the slaughter area to the moment the meat is delivered to the customer, every step must be standardized."
