Description

The novel foodstuff mono-frozen machine

One, technical field

It is mono-frozen machine that the utility model relates to a kind of single quick-freezing machine, and the novel foodstuff mono-frozen machine that especially a kind of defrosting is easy, efficient is high, drying loss is few, energy-conservation belongs to freezing processing technique field.

Two, background technology

The subject matter that existing food individual quick freezing machine exists has, 1, the frosting problem of evaporimeter: blocked up frost layer has a strong impact on the heat exchange effect generation of evaporimeter, cause cooling slowly, power consumption increases, and influences the output of food product refrigeration processing and the normal cooling in quality and the refrigerating process; When 2, the frost layer reaches certain thickness, must shut down evaporimeter is carried out the defrosting processing, need defrosting once in general 4-5 hour, each defrosting influenced the ordinary production progress, and causes the labourer to waste about 2 hours; 3, drying loss is big, and the intensity of wind is poor, and the wind speed adjustable extent is little, and freezing food scope is had significant limitation.

Three, the content of utility model

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of defrosting in process of production, efficient height, few, the energy-conservation novel foodstuff mono-frozen machine of drying loss are provided.

For achieving the above object, the utility model is achieved in that a kind of novel foodstuff mono-frozen machine, comprise shell and the evaporimeter that is positioned at it, the air delivery duct, the circulating fan that is equipped with in the plenum chamber machine plenum chamber, return air chamber and conveyer, its special character is, evaporimeter by several independently evaporator unit form, wherein there is one to be standby evaporator unit, the periphery of each evaporator unit all is provided with peripheral backplate, have air outlet and air outlet that air door is housed on it, the air outlet of each evaporator unit and air outlet all are communicated with respectively at the plenum chamber and the return air chamber of mono-frozen machine.

In order to adjust wind speed, regulate air quantity and to change air supply direction, can be in the air delivery duct be provided with one to two movably air channel barrier, forming 2-3 sizable air compartment, but and the bypass that has the adjustment air quantity of several switches and change air supply direction seal.

For reducing the drying loss of food, can with the return air chamber compartment, above food, form the higher cold air stream of relative humidity, by the air door of preserving moisture in the return air chamber of mono-frozen machine to reach the purpose that reduces drying loss.

The utility model compared with the prior art, the advantage that has has: (1), can be in the device fabrication running replace defrosting and handle to evaporimeter, do not influence production, guaranteed the output and the quality of frozen food; (2), owing to be provided with the air door of preserving moisture and carry out compartment, the hydrone in the cold wind changes direction, forms the higher cold air stream of relative humidity above food, has reduced the drying loss of food, has improved the uniformity coefficient of fast food freezing; (3), the wind speed adjustable extent is wide, the size by regulating air compartment and utilize bypass to seal to regulate different wind speed with frequency converter and change the direction of air-supply has not only guaranteed quality but also saved energy consumption; (4), because evaporimeter is divided into several unit, reduce the tube side resistance, increased front face area, reduced windage, reduced the temperature difference between evaporating temperature and the storehouse temperature, improved the efficient of compressor, the reduction drying loss.

Five, the specific embodiment

For better understanding the utility model, it is described in further detail below in conjunction with drawings and Examples.

With reference to Fig. 1-Fig. 9 as seen, novel foodstuff mono-frozen machine described in the utility model mainly is by shell 1 and the evaporimeter that is positioned at shell, the circulating fan that is equipped with in plenum chamber and the plenum chamber, return air chamber, the conveying arrangement of air delivery duct and conveying food is formed, evaporimeter by several independently evaporator unit 2 form, a standby evaporator unit is wherein arranged, the periphery of each evaporator unit 2 all is provided with peripheral backplate, drip tray 3 is housed below, each evaporator unit all is provided with an air inlet 4 and an air outlet 5, and but the air door 6 of switch is housed respectively, circulating fan 8 is installed in the plenum chamber 7; The air delivery duct 9 of mono-frozen machine is provided with one to two movably air channel dividing plate 10 and several bypass air ports 11, air channel dividing plate 10 is divided into air compartment the air compartment of 2-3 adjustable size, in order to regulate wind speed, it is the directions that are used for regulating air quantity and change air-supply that bypass seals 11; In order to reduce the drying loss of food, the air door 12 of preserving moisture is housed in the return air chamber of mono-frozen machine, with the return air chamber compartment, to change the direction of hydrone in the cold wind, above food, form the higher cold air stream of relative humidity, thereby reach the purpose that reduces drying loss, owing to above food, form certain air turbulence, improved the uniformity coefficient of fast food freezing greatly simultaneously.

When bringing into operation, check whether the air inlet 4 of evaporator unit and the air door 6 of air outlet 5 are opened, close advancing of standby evaporator unit, the air door 6 of air outlet, ON cycle air-cooler 6, the normal feed flow of evaporimeter freezes simultaneously, cold wind arrives air delivery duct 9 from plenum chamber 7 by circulating fan 8, want the food of quick-frozen again by guipure or strip process, by carrying out heat exchange with food, the temperature of cold wind raises, and air door 12 enters return air chamber 13 through preserving moisture, pass through the return air inlet of each evaporator unit again, after the evaporator unit refrigeration,, arrive plenum chamber 7 at last again, the operation that so moves in circles to air outlet 5.

When needing defrosting, close the feed flow of an evaporator unit, open the import and export air door and the supplying valve of standby evaporator unit simultaneously, the beginning feed flow, treat 2-5 minute after, close advancing of the evaporator unit of wanting defrosting, the air door 6 and the supplying valve of air outlet, begin that evaporimeter is carried out defrosting and handle, defrosting finishes, and opens about 1/4th of air door 6, wait for 2-3 minute, the water of evaporimeter is dried up, open supplying valve, air door 6 is all opened the evaporimeter feed flow, carry out normal circulation, and needn't stop to produce defrosting, by that analogy, each unit is carried out defrosting handle, after defrosting finishes, with advancing of standby evaporator unit, outlet air door and supplying valve are closed, and carry out defrosting and handle, and use during in order to defrosting next time again, do not influence ordinary production, guaranteed the output and the quality of frozen food; When output is big, can open standby evaporator unit, to increase refrigerating capacity, reach increase output, widened the scope of frozen food greatly, have high using value.
