Description

A kind of vacuum thawing device

Technical field

This utility model is related to a kind of food processing apparatus, and specifically the meat product after freezing is thawed is true Empty thawing apparatus.

Background technology

It is known that the meat such as Carnis Gallus domesticus, Carnis Sus domestica, in order to extend fresh keeping time, is typically necessary and is freezed.After freezing Meat is required for carrying out defrosting process before use.

At present, conventional thawing apparatus in food-processing industry is divided into electric thawing device and two kinds of air thawing device.Electricity Thawing apparatus includes defrosting plate and the heater for heating defrosting plate；During use, food to be thawed is placed into defrosting On plate, then start heater, so that the temperature of defrosting plate is raised rapidly, thus transferring heat to food, making food defrosting. Operationally, food is directly contacted this thawing apparatus with the defrosting plate of high temperature, food surface oxidizable so that thaw after food Second-rate.The course of defrosting of air thawing device is exactly that food is placed in the air so as to heat in absorption air Slowly complete to thaw, the time that whole course of defrosting consumes is longer, and food surface is easily polluted by microorganism.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of vacuum thawing device, is thawed using vacuum thawing device Food afterwards, quality preferably, does not have microorganism pollution.

For solving the above problems, provide technical scheme below：

The feature of vacuum thawing device of the present utility model is including vacuum chamber, and the side wall of this vacuum chamber has normal pressure mouth, Constant pressure valve had on normal pressure mouth, vacuum extractor, steam generating device and pressure gauge arranged at the top of vacuum chamber, the taking out of vacuum extractor Vacuum port is connected with vacuum chamber, and the vapor outlet port of steam generating device is connected with vacuum chamber.Described vacuum indoor useful in Hold the sliding machine treating defrosting food, there is handle the side of sliding machine, this handle corresponding vacuum chamber side wall has for The door opening of turnover sliding machine, this door opening has rolling screen door.After described rolling screen door and constant pressure valve closing, vacuum chamber is in closed.

Wherein, described rolling screen door includes being fixed on the doorframe of described door opening surrounding, and the upper side frame of this doorframe has roller shutter shell, There are motor and the rotating shaft being longitudinally arranged along doorframe upper side frame in this roller shutter shell, be in rotate shape cooperation between rotating shaft and roller shutter shell, described Motor is used for drive shaft and rotates.All there is guide groove on the opposite face of two vertical frames of described doorframe, between two guide grooves, have roller shutter Piece, is in that slipper seal shape coordinates between the vertical edges of rolling shutter and the bottom land of corresponding guide groove, the upper end of rolling shutter is fixed on described turning On axle.The upper surface of described doorframe lower frame has the groove for accommodating rolling shutter bottom, and the bottom land of this groove has sealing strip.

Take above scheme, there is advantages below：

Because vacuum thawing device of the present utility model includes vacuum chamber, the side wall of vacuum chamber has normal pressure mouth, normal pressure mouth On have constant pressure valve, vacuum extractor, steam generating device and pressure gauge are arranged at the top of vacuum chamber, and there is sliding machine vacuum interior, There is handle the side of sliding machine, and this handle corresponding vacuum chamber side wall has the door opening for passing in and out sliding machine, this door opening On have automatic shutter, the side wall of vacuum chamber has controller, the drive of vacuum extractor, steam generating device and automatic shutter Dynamic device is all connected with controller by wire.During use, first open rolling screen door；Then, pull out sliding machine, will be to be thawed Food is placed on sliding machine；Afterwards, sliding machine is pushed into vacuum interior, closes rolling screen door and constant pressure valve, startup is taken out Vacuum equipment and steam generating device, under certain vacuum, steam runs into the water release after the food thawing, condensing into The latent heat of vaporization is absorbed by food to be thawed, and food to be thawed constantly absorbs the latent heat of vaporization thus completing to thaw；Finally, wait to solve After the completion of jelly, close vacuum extractor and steam generating device, open constant pressure valve, by observing pressure gauge, treat that vacuum interior is extensive After multiple normal pressure, open rolling screen door, pull out sliding machine, take off food.Operationally, food need not for this vacuum thawing device Contact with high-temperature medium, so that food surface is not oxidizable.And, the microorganism that can survive under vacuum condition is less, from And avoid the problem that food in course of defrosting is subject to microorganism pollution.

Brief description

Fig. 1 is a kind of structural representation of vacuum thawing device of the present utility model；

Fig. 2 is the I portion enlarged drawing of Fig. 1.

Specific embodiment

Below in conjunction with accompanying drawing, this utility model is described in further detail.

As depicted in figs. 1 and 2, vacuum thawing device of the present utility model includes vacuum chamber 1, on the side wall of this vacuum chamber 1 There is normal pressure mouth 2, normal pressure mouth 2 has constant pressure valve 3, the top of vacuum chamber 1 is provided with vacuum extractor 4, steam generating device 5 and pressure Power table 6, the vacuum orifice of vacuum extractor 4 is connected with vacuum chamber 1, the vapor outlet port of steam generating device 5 and vacuum chamber 1 phase Connection.It is provided with for holding the sliding machine 7 treating defrosting food in described vacuum chamber 1, the side of sliding machine 7 is fixed with draws Handss 8, this corresponding vacuum chamber 1 side wall of handle 8 have the door opening for passing in and out sliding machine 7, this door opening have rolling screen door.Described After rolling screen door and constant pressure valve 3 closing, vacuum chamber 1 is in closed.
