Dehe Zi Beijing Artificial Environment Technology Co., Ltd

Fruits and vegetables fresh-keeping / ripening Meat and Seafood Frozen Storage Pharmaceutical and Medical Device Cold Storage Food Cold Storage and Freezing Warehouse

Processing workshop

Function: Sort and process packaging products.

Temperature requirement: 0 ℃ to 15 ℃ (for conventional high and low temperature processing workshops).

Storage of products: Temporary storage of food to be processed (such as meat, fruit and vegetable sorting and packaging).

Characteristics: Temperature and humidity affect processing efficiency and product quality, and cleaning and disinfection measures need to be coordinated.

Freezing Store

Function: Used for storing products with low temperature requirements such as food, meat, and aquatic products. Through precise refrigeration, it maintains a constant low temperature inside.

Temperature requirement: -18℃ to -25℃, for low-temperature foods (such as frozen meat, aquatic products, seafood, etc.).

Storage products: frozen meat (pork, beef), frozen fish, ice cream, quick-frozen food (dumplings, rice dumplings).

Characteristics: High energy consumption, commonly used in food processing; small ice crystals, reducing cell damage, with a shelf life of several months or even years.

Quick Freezing Store

Function: Quickly freeze products (below -30 ℃) to reduce the damage of ice crystals to cell structure.

Temperature requirement: -30 ℃~-40 ℃.

Storage products: low-temperature freezing of meat, fruits and vegetables, aquatic products, seafood and other products.

Characteristics: Avoid generating large ice crystals between cells; Reduce intracellular water leakage and minimize juice loss during thawing; The time for concentrated solutes and food tissues, colloids, and various components to come into contact with each other within cellular tissues is significantly reduced, and the harm of concentration is minimized; Quickly lowering food to below the temperature of microbial growth activity is beneficial in resisting microbial growth and biochemical reactions; The short residence time of food in freezing equipment is beneficial for improving equipment utilization and continuous production.

Ultra-low Temperature Cold Storage

Function: Used for ultra-low temperature storage of valuable deep-sea aquatic products or biological products to prevent loss or denaturation of biological activity.
Temperature requirements: -45 ℃ to -60 ℃. For tuna, temperatures should be below -50 ℃.
Storage products: tuna, etc.
Characteristics: High equipment investment, significant energy consumption, and the need for special insulation materials.
