Vacuum Freeze Drying Chamber

Vacuum freeze-drying applications
One, Applications of Freeze-Dried Products:
Freeze-dried foods have relatively high nutritional value and are relatively fresh. The earliest food items were primarily used in special industries such as military supplies, fieldwork, mountaineering, and aerospace. Currently, as people's living standards have improved, convenience food industries, soup processing industries, instant beverages, and nutritional supplements have become more widespread.
Two, Principle of Process:
The basic principle of vacuum freeze-drying is to obtain dry products through processes such as freezing, rapid freezing, vacuum, and heating at low temperatures, using a sublimation drying dehydration method. The greatest preservation of the original product's nutritional components, color, shape, taste, and ease of storage.
Three, Process Flow:
    Preprocessing (raw material cleaning, bleaching, drying, etc.) — finishing (slicing, color preservation, palletizing) — freezing (freezing in a freeze-drying chamber) — freeze-drying (heating, vacuuming, refrigerating) — unloading packaging (drying complete, unloading, packaging) — selecting sub-packaging (metal inspection, selection, packaging).
Four, Equipment Process:
Preprocessing equipment (cleaners, ironing machines, feeders, vibration plugs, etc.) — finishing equipment (shell removal, slicing, pulping, feeding, etc.) — freezing equipment (freeze tunnel) — vacuum freeze-drying equipment (freeze-drying equipment, heating equipment, refrigeration equipment, control equipment) — unloading room — select the equipment. The entire device is connected via transmission tracks.
Typical example: Zhengzhou Miss You Co., Ltd.
Construction date: May 18, 2019, Xinzheng, Zhengzhou, Henan.
Project Overview: Spanning 68,000 square meters, steel structure warehouse, clear height 12 meters, freeze-dried production line FD200㎡, 10 lines
Construction period: 120 days, commissioning and cooling cycle: 45 days.
  Equipment parameter information:
  Refrigeration uses a dual-stage semi-enclosed screw parallel compressor paired with an outdoor heat dissipation evaporative condenser: 10 units in a 200㎡ freeze-drying chamber with an internal temperature of -35°C.
Operating conditions: -42℃/35℃, with a project cooling capacity of 7000KW, suitable for rapid freezing low-temperature conditions.
The project employs a centralized control system, refrigeration clouds, and is designed to last for 20 years.
