In our countryEdible mushroom resourcesveryrichness，of whichIncluding wild edible mushrooms and cultivated edible mushrooms，edible fungibe rich inProteins and amino acids，taste deliciousDeeply loved by consumers! With the upgrading of cultivation and consumption habits, the use of edible mushroom freeze-drying processing technology for vacuum freeze-drying of edible mushrooms can preserve their original color, aroma, taste, shape, and nutritional components, and can be stored for a long time at room temperature with good rehydration properties. Production of freeze-dried edible mushroomsThe selection of food freeze-drying machine is very important, hereinafter referred to as edible mushroom freeze-drying machine for a brief introduction.

The freeze-drying processing technology for edible mushrooms utilizes the principle of sublimation to clean, cut, sterilize, and treat the mushroomsAfter entering the edible mushroom freeze-drying machine for in-situ pre freezing, the pre freezing temperature-45℃, pre freezing time180Minutes, then the freeze dryer is used for one drying, with drying temperatures divided into-25℃~25Temperature rise rate control operation is carried out in eight temperature ranges of ℃, and the drying operation time is controlled within one time720Minutes, vacuum controlled at35PAWithin. After one drying session, perform analytical drying, which includes the following steps:30℃~60℃, operating time is500About minutes, the vacuum control is25PAabout. pass throughPLCThe entire vacuum freeze-drying process is fully automated by electronic control.

The selection of freeze-drying machines for edible mushrooms such as shiitake mushrooms, fungus, cordyceps, morel mushrooms, and matsutake mushrooms requires consideration of the following technical indicators and configuration requirements:

1Partition temperature control range:-50~+70℃；

2Uniformity of partition temperature: ±1℃；

3Condensation limit temperature:-70℃；

4Ultimate vacuum degree:2.5PA

5Box, partition, material tray material:304stainless steel;

6Refrigeration system: The compressor and refrigeration accessories are selected from imported brands;

7Vacuum system: Choose large or imported brand vacuum pump sets;

8Electronic control system: Select imported brandsPLCAnd electronic accessories.

The edible mushroom freeze-drying machine needs to have process settings and modifications, temperature rise rate control, vacuum fine adjustment control, data recording and storage, freeze-drying curve query, password management and permission functions, remote operation and monitoring, and other functions to meet the requirementsGMPFood requirements, widely used in freeze-drying processing and production of various edible mushrooms!
