Cold storage dehumidifier is often used in fruit and vegetable storage and vegetable air conditioning storage, high temperature storage cold storage, medical storage cold storage, ice skating rink, ski resort and other relatively low temperature environment。Among them, the humidity of pharmaceutical cold storage and food cold storage will affect the normal use and safety of food and drugs。In the relatively strict cold storage or skating rink, it is generally necessary to configure dehumidifier。Low temperature environment dehumidifier selection: Generally common dehumidifiers are ordinary dehumidifier, low temperature dehumidifier and rotary dehumidifier (other models are omitted)。Among them, ordinary dehumidification
The use of various frozen machine: ① flat net belt frozen machine: suitable for meat, prepared food, aquatic products, dishes, ice cream and so on。It is a basic universal quick-freezing machine。Its output is 100kg/h - 3000kg/h。 ② Multi-functional vibrating net belt quick-freezing machine: a dynamic device is added on the basis of the universal flat net belt monomer quick-freezing machine。In addition to the characteristics of the universal flat mesh belt monomer quick-freezing machine, it is also suitable for the freezing of granular food monomer。③ Tunnel pre-cooling quick-freezing machine: Creatively combine pre-cooling and quick-freezing into one
When we build the air conditioning of cold storage or supporting workshop, we will design and use chiller in the high temperature area and the low temperature area。One of the four major components of refrigeration system (refrigeration host, condenser, throttling device, evaporator)。Chiller schools will also be based on the design of the use of refrigeration media, habitually divided into fluorine refrigeration fans, ammonia refrigeration fans, ethylene glycol (refrigerant) refrigeration fans。When our cold storage practitioners give you the quotation of fluorine refrigeration fans, they will write DL, DD, DJ with numbers, numbers
In order to protect the safe operation of the refrigeration system, the ammonia (fluorine) storage device, condenser, intercooler, etc., is provided with a safety valve。The following is a common safety law model to explain the meaning of the safety valve, for replacement reference。Safety valve model: A42F-25C, the model is explained as follows: A represents the safety valve, 4 represents the flange type, 2 represents the opening mode is fully opened, F represents the sealing surface is tetrafluorsurface, 25 represents the nominal pressure of the valve body is 2.5MPa, C means the valve body is carbon steel
This standard specifies the design, construction, operation and management of cold storage and the safety requirements when the refrigeration system is shut down for a long time。This standard is applicable to the direct refrigeration system and the cold storage of indirect refrigeration system with ammonia, halogenated hydrocarbons and other refrigerants。Other types of cold storage and refrigeration systems can be followed。This standard does not apply to indoor prefabricated cold stores sold as products。
Common food fruit, vegetable and meat storage temperature, humidity and insurance cycle: fruit and vegetable storage temperature: fruit generally 0-14 ° C, vegetables generally -2-20 ° C, cooked food generally 0-10 ° C, bread cake generally 6-18 ° C, sugar and wine generally 0-16 ° C。 Refer to the table below
