Thawing Machine Defrost Beef And Chicken 1t/time To 30t/time

First cold chain the low-temperature high-humidity air to blow the surface of frozen products circularly and evenly; Control the defreezing time, temperature and humidity by stages; the frozen products can be unfrozen slowly and homogeneously. Defreezer is one of our most important machine

一、Design Principle

Product type:-18℃【Pork,Chicken,Beef】Frozen PCS

 Defrosting Method:Defrosting Carts

 Defrosting Capacity:5T each time/-18℃【Pork,Chicken,Beef】Frozen PCS

 Defrosting Time:8~12 h each time

 Quantity:1 set

二、 Defrosting Tech Summary                                              

Our technical theory is on the basis of using low temperature and high humidity air to blow the surface of frozen products recycling and equally to thaw the frozen products.At the same time,this machine can automatic use PLC to control the temperature and time by stage .

三、Main Equipment Structure    

1、Internal structure

With air support, water collection tray, wind deflector plates, air board, fan bracket panels, wind prevent board, made of 304 stainless steel;

Cold storage dedicated fan axial fans, shell and bracket are made of 304 stainless steel;

Motor is for moisture &low temperature resistance , cast aluminum blades;

Evaporator with efficient use of surface oxidized aluminum machining brass, stainless steel shell;

Dispenser dispensing evenly to ensure frost uniform, clear airflow

3、 Heated & humidification system

Method 1: water steam : The heat conduction through the conduit into inner thawed room,and water steam completed by reduced pressure and steam atomization of double line.Method 2: One set Italy humidification pump. keep thawing room environment humidity. Winds circulating blows evenly through the frequency wind blows between thawing temperature and humidity.

4、Refrigeration system

Refrigeration units; Germany Bitzer-8.2Y 1;

Refrigeration valves:DANFOSS;

Refrigerant and refrigeration oil:;

Freon refrigeration cooling stainless steel pipe and copper pipe, cooling pipe insulation adopted sleeves approach to ensure uniform, seamless and insulation effect;

Storage temperature setting range 20 ℃ ~ -0 ℃, evaporation temperature -10 ℃. Condensing temperature 38 ℃, cooling capacity 6.5KW

5. Electrical Control System

Siemens PLC microcomputer control;

 Germany Fascino control program technology;

control panel: Taiwan 10-inch color touch screen interface

Parameter settings: Transducer parameter settings are according to temperature of center,surface and interior, inside humidity sensor signal

electrical components are Schneider brand;

Using copper wire waterproof cable.

四、Technical Standard                                              

low temperature and high humidity air is the main system and refrigerating system is as a auxiliary system.The PLC can control the whole system to keep energy-saving and scentific when defrosting.

Raw meat standard:

  After defrosting ,the effects of frozen products keep balance,no oxidization and gray line.

  After defrosting,muscular tissue is full luster and elastic.

  After defrosting,the lost rate of protein juice is less  1%【raw

  After defrosting,the temperature in the center could be set at -2±1℃and Particular case is particular setting.

Defrosting type can be set in several stages and control the process accurately ,time controlled at 8-12H according to the different situation.

五、Manufacture & Advantages                                

1、Equipment advantages Advanced technology: German technology, combined with years of production experience,also developing new and improved equipment now. Unique air distribution way and air volume at different thaw periods, with a sub-component of air, and then a more detailed, uniform and accurate air circulation to ensure the best product thawing effect.

Material guarantee: materials comply with food hygiene requirements of 304 stainless steel plate and pipe, (wall panels, air board, corrugated ceiling panels, beams, columns, etc., see the thawing machine parts parameters and price), in order to meet the hygiene needs, structural strength and service life.

2、 Thawing advantages

Thaw technique is to use low temperature and high humidity of circulating air blowing, make the product surface form a uniform air distribution, PLC automatic segmentation by controlling temperature and time to achieve product thaw. Low humidity thawing equipment not only save costs, but more important is to maintain freshness of original organoleptic characteristics,fully meet the market fresh sailing after thawing.

thawing process can be phased control

maintain the original color and elasticity of the product

 low water loss rate, the minimum protein loss

 product thaw quickly and evenly, low energy consumption

controllable low temperature, inhibit microbial growth

 high efficiency unit area using

 can be used as fresh cold storage facilities
