Description
Technical field
The present invention relates to a kind of food processing apparatus, the vacuum thawing device specifically meat product after freezing thawed.
Background technology
It is known that the meat such as Carnis Gallus domesticus, Carnis Sus domestica is in order to extend fresh keeping time, it is typically necessary and carries out freezing.Meat after freezing is required for carrying out defrosting process before use.
At present, conventional in food-processing industry thawing apparatus is divided into electric thawing device and two kinds of air thawing device.Electric thawing device includes defrosting plate and for heating the heater of defrosting plate；During use, food to be thawed is placed on defrosting plate, then starts heater, make the temperature of defrosting plate raise rapidly, thus transfer heat to food, make food defrosting.Operationally, food directly contacts this thawing apparatus with the defrosting plate of high temperature, and food surface is oxidizable so that after defrosting, food is second-rate.Food is placed in air by the course of defrosting of air thawing device exactly so that it is absorbing the heat in air and slowly complete to thaw, the time that whole course of defrosting consumes is longer, and food surface is easily polluted by microorganism.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of vacuum thawing device, the food after using vacuum thawing device to thaw, and quality is preferable, does not has microorganism to pollute.
For solving the problems referred to above, it is provided that techniques below scheme:
The feature of the vacuum thawing device of the present invention is to include vacuum chamber, normal pressure mouth is had on the sidewall of this vacuum chamber, constant pressure valve is had on normal pressure mouth, vacuum extractor, steam generating device and Pressure gauge are arranged at the top of vacuum chamber, the vacuum orifice of vacuum extractor is connected with vacuum chamber, and the vapor outlet port of steam generating device is connected with vacuum chamber.Having in described vacuum chamber for holding the sliding machine treating defrosting food, there is handle the side of sliding machine, the vacuum chamber sidewall that this handle is corresponding has the door opening for passing in and out sliding machine, this door opening has rolling screen door.After described rolling screen door and constant pressure valve are closed, vacuum chamber is closed.
Wherein, described rolling screen door includes the doorframe being fixed on described door opening surrounding, and the upper side frame of this doorframe has roller shutter shell, has motor and the rotating shaft being longitudinally arranged along doorframe upper side frame in this roller shutter shell, coordinating in rotation shape between rotating shaft with roller shutter shell, described motor rotates for drive shaft.All having guide groove on the opposite face of two vertical frames of described doorframe, have rolling shutter between two guide grooves, coordinate in slipper seal shape between the vertical edges of rolling shutter with the bottom land of corresponding guide groove, the upper end of rolling shutter is fixed in described rotating shaft.The upper surface of described doorframe lower frame has for accommodating the groove bottom rolling shutter, and the bottom land of this groove has sealing strip.
Take above scheme, have the advantage that
Owing to the vacuum thawing device of the present invention includes vacuum chamber, normal pressure mouth is had on the sidewall of vacuum chamber, constant pressure valve is had on normal pressure mouth, vacuum extractor, steam generating device and Pressure gauge are arranged at the top of vacuum chamber, sliding machine is had in vacuum chamber, there is handle the side of sliding machine, the door opening for passing in and out sliding machine is had on the vacuum chamber sidewall that this handle is corresponding, automatic shutter is had on this door opening, controller, vacuum extractor, steam generating device is had all to be connected with controller by wire with the driving means of automatic shutter on the sidewall of vacuum chamber.During use, first open rolling screen door；Then, pull out sliding machine, food to be thawed is placed on sliding machine；Afterwards, sliding machine is pushed in vacuum chamber, close rolling screen door and constant pressure valve, start vacuum extractor and steam generating device, under certain vacuum, steam runs into after the food thawed, and the water release latent heat of vaporization condensed into is absorbed by food to be thawed, and food to be thawed constantly absorbs the latent heat of vaporization thus completes to thaw；Finally, after defrosting completes, close vacuum extractor and steam generating device, open constant pressure valve, by observing Pressure gauge, after recovering normal pressure in vacuum chamber, open rolling screen door, pull out sliding machine, take off food.Operationally, food is without contacting with high-temperature medium, so that food surface is the most oxidizable for this vacuum thawing device.And, the microorganism can survived under vacuum condition is less, thus avoids the problem that in course of defrosting, food is polluted by microorganism.
