Uzbekistan Fruit and Vegetable Cold Storage Construction-Vegetable Cold Storage Case

Project Overview

Uzbeks Food Company has an inventory of 1,000 tons. The cold storage covers an area of 900 square meters and the size is 60*15*7 meters. The warehouse body is rectangular, and the design warehouse body is divided into one with a storage capacity of 300 tons and two with a storage capacity of 200 tons. There are two 100-ton capacity, one low-temperature sorting and packaging workshop, and one low-temperature packaging sorting workshop, covering an area of 50 square meters.

Cargo description

The temperature of the goods is 30 degrees Celsius, and the temperature in the warehouse is designed to be 0 degrees Celsius. The use is to adjust the temperature according to different goods. The cooling time is 24 hours. The daily purchase amount is 8-10. The more than 100 tons, 10 people work for three hours a day. The lighting heat is 2.3W/M2, and the cargo heat is kohlrabi as a reference. The storage enthalpy is 428KJ/kj, the final enthalpy is 331KJ/KG, the moisture content is 90%, and the freezing point temperature is -0.9 degrees Celsius.

Library structure and heat preservation instructions

The warehouse body building adopts a steel-concrete structure, and the warehouse temperature is designed to be 0 degrees Celsius. The look-up table calculates that the thickness of polyurethane double-sided color steel insulation and anti-fogging is 66MM, so 100MM polyurethane insulation board is used, pentahedron insulation, and the bottom is staggered with 100mm thick extrusion The board is insulated with 100mm thick concrete moisture-proof layer.

Unit configuration

Based on the above description, it is calculated that the cooling capacity of the five warehouses is 45×15×7m, and the cooling capacity of the sorting and packaging workshop is 15×15×7m. Considering that the warehouses are called centralized, from the perspective of economy, reliability, and comprehensiveness, 5 The intermediate refrigerator adopts a piston-type fluorine system sub-cooling compressor, equipped with Bitzer parallel units, a large-scale cold-air condenser, and a sorting and packaging workshop independently adopts a Bitzer piston-type air-cooled compressor.

Because the parallel control system can adjust the compressor start and stop or unload according to changes, control the start and stop of the economizer according to the operating state of the system, and control the start and stop of the sub-cooling condenser according to the change of condensing pressure. So choose the parallel system. Two banks and one machine or one bank and one machine can also be selected independently.

Cool down

After the cold storage is installed and debugged, begin to cool down in sections. Because the design temperature is 0-5 degrees Celsius, the normal temperature at start-up is 28 degrees Celsius, and the temperature is lowered from normal temperature in three periods of time. The first temperature section is normal temperature to 12 degrees, the second section is 5-8 degrees, and the third temperature is 0- 3 degrees, the last temperature section -3 to 0 degrees, each temperature section automatically starts and stops according to the set value.

Refrigerant: R404A

Air cooler: 300 tons warehouse with 6 DD air coolers, 200 tons with 4 DD air coolers, 100 tons with 4 DD air coolers, and two DD air coolers for the sorting and packaging workshop

Design and installation of large-scale food cold storage for milk tea

Cold storage project: Large-scale food cold storage for milk tea (Phase 5)

Cold storage room temperature: -18℃, 2~6℃, 5~9℃, 15℃

Cold storage capacity: 3000m³, 2 freezers, 3 cold storages, 1 return room

Cold storage use: unified storage of large quantities of milk tea raw materials, food materials and other cold storage

The milk tea (Phase 5) large-scale food cold storage design and installation project in Hubei has been completed and debugged recently. Nearly 3000m³ food cold storage with both refrigeration and freezing functions has been put into formal use, and the operation effect has once again been unanimously recognized by customers.

Hanyang Technology introduced that the design and installation of the food cold storage is to store various raw materials for milk tea, ensuring freshness, hygiene and safety from the source. The 3000m³ food cold storage includes 3 cold storage (2~6℃ and 5~9℃), 2 freezer storage (-18℃) and 1 return room (15℃). To match the actual situation of the customer’s actual warehouse using forklifts for inbound and outbound goods, the food cold storage adopts a pentahedral structure, that is, the five sides of the top and wall surfaces are insulated with polyurethane insulation materials, while the ground side is separate Do XPS waterproof and air insulation.
