  • Since ancient times, humans have been known to use cold for life, by giving the animals exposed to freezing cold objects such as ice used to preserve the products they hunted it is the natural cooling. But to make arbitrary cold temperatures and keep the temperature in an arbitrary time, the need for cooling systems up to date techniques of cold tao.Cho growing strong and is widely used in the economic importance and active support for such industries as:
    - Branch processing technology and food preservation
    - In heavy industry: mold cooling
    - In health: processing and storage of medicinal products
    - In the chemical industry: control of chemical reactions
    - In the field of air conditioning for production and life.

    II. GRANT PURPOSE, wintering

    In order to keep the long-established food supply and distribution for the national economy, it must be frozen and stored frozen to keep food at a low temperature (-180C ÷ - 40 C). Because the lower the temperature of the microbial food as rancid as inhibited, the resolution process is slow. So that would keep the food is not broken for a long time.

    III. MISSION of the scheme
    Design frozen system, stored frozen pork products with the following parameters:
    1. Freezing:
    - Environmental quality: R22
    - Product maintenance: Pork
    - Capacity: E = 2.5 tons / batch
    - Meat Temperature input: = 18
    - Temperature of meat output: TTB = -15
    - Freezing time: τ = 11 h
    - Room temperature freezers: = -35
  • Filters will filter residue and moisture in the system to limit the moisture in the refrigeration system rules.
