Abstract
This invention discloses a food freezing system with vacuum mode, which contains vacuum room, refrigeration system, vacuum pump, cold trap, triple valve, at least one tank and bowl cover and sealing ring. Bowl cover covers the tank and there is a sealing ring between them. The tank is connected with the triple valve by canal. One head of the triple valve goes to the atmosphere, and the third head is joined with the vacuum room through canal. There is cold trap in the vacuum room and it is joined with refrigeration system. When the triple valve leads to the vacuum room, pressure in the tank falls quickly. The food raw materials solution will evaporation boiling when its bubble point pressure is reached, and it will release heat and cool down, so frozen food is form quickly. This equipment is small and cheap; it consumes little energy but refrigerate quickly. The frozen food is fine and glossy, it tastes good and clean, also it is convenient to process.
Description
Technical field
The present invention relates to a kind of food refrigeration, refrigerating plant, especially a kind of food refrigeration, refrigeration system that adopts vacuum mode.
Background technology
Summer has set in, no matter be in large-scale Food Fair, cold food shop, or the retail stand in streets and lanes, various frozen food have attracted numerous consumers, make domestic cold drink consumption be the trend of obvious rising.Nowadays, frozen food all has market preferably throughout the year.And present people also pay attention to the nutritive value of frozen food more.Because each one taste difference, the making raw material of the frozen food nutritional labelings such as extract of ascorbic fruit, vegetables, honey, kernel, protein, fat, carbohydrate and Chinese herbal medicine (as be rich in) there is different requirements, make the status of frozen food in people's daily bread consumption that variation take place, it has incorporated heavily nutrition, high-grade level.
The production equipment of frozen food, usually adopt conventional freezing method, promptly produce cold, remove the raw material of cooling quick-freezing food by refrigeration machine, these production equipment kind models are many, function is complete, and speed of production, work efficiency, precision, automaticity, complete property are all higher.But it costs an arm and a leg, and enterprise's one-time investment is big.Owing to be to produce in batches, be difficult to accomplish each consumer's suitable taste.Simultaneously, the production equipment housekeeping also has suitable difficulty.
At present, also having a kind of cooling, freezing method is vacuum cooled.The principle of vacuum cooled is: the boiling point of solution reduces along with the decline of pressure, the solution of normal temperature is in the pressure vessel, when pressure reaches the corresponding saturation pressure of solution temperature of living in, water will evaporate boiling, the water evaporation needs to absorb a large amount of latent heats of vaporization, this heat is from solution itself, thereby solution temperature is reduced.Adopt the equipment of vacuum cooled to mainly contain vacuum cooled freshness preserving equipment, vacuum freeze drier.A kind of external cold source type vacuum cooled freshness preserving equipment is disclosed as Chinese patent CN03228870.0; CN97100964.3 discloses a kind of food vacuum frozing drier.They are by refrigeration system, vavuum pump, and water vessel formations such as (cold-traps) has been saved refrigeration unit, makes complete equipment comparatively light, and investment saves, and operating cost reduces.Though vacuum cooled has many good qualities, on the production equipment of frozen food, also be not applied, particularly adopt the vacuum cooled mode to make frozen food, as frost, ice cream etc.
Summary of the invention
The present invention is in order to adapt to the various requirement of current people to frozen food, and provide a kind of system that adopts the vacuum mode cooling quick-freezing food, this device is small and exquisite, cheap, energy consumption is low, have very fast, the frozen food quality exquisiteness of cooling cooling velocity, mouthfeel is good, sanitation and hygiene, characteristics such as easy to operate.
For realizing that the technical scheme that purpose of the present invention adopts is: a kind of device that adopts the vacuum mode cooling quick-freezing food comprises vacuum chamber, refrigeration system, vavuum pump, cold-trap, triple valve, at least one glass jar and bowl cover, sealing ring.Bowl cover is stamped on top at the cup jar, is provided with sealing ring between cup jar and the bowl cover, and the cup jar links to each other with triple valve by pipeline, and one of triple valve leads to atmosphere, and the other end links to each other with vacuum chamber by pipeline, and vacuum chamber is built-in with cold-trap, and cold-trap links to each other with refrigeration system.
Be placed with the cup that fills raw-food material solution in the cup jar; Triple valve is manually control or controls triple valve automatically.
Characteristics of the present invention are:
1. the cooling cooling velocity is very fast, and conventional cool-down method relies on the heat conduction, and temperature fall time is long, and the present invention is by discharging the latent heat of vaporization, generally just can dropping to temperature required in a few minutes;
2. frozen food quality exquisiteness, because solution cooling when boiling, lowering temperature uniform everywhere in the solution can make the tiny goods of ice crystal with the present invention, has good mouthfeel;
3. can be according to different raw material and the proportionings of the instant modulation of each one taste, instantly promptly use;
4. sanitation and hygiene, conventional method of making refrigerated products will contact various utensils on streamline, and the sanitary conditions of these utensils directly have influence on food.And institute of the present invention edible raw material is placed in the disposable raw material cup, just can use through the cooling of finding time, and is convenient and healthy;
5. easy to operate, the cup that raw-food material is housed is placed in the cup jar, and cover lid, switch three-way valve be cooling immediately just, and technology is very simple;
6. install small and exquisitely, cheap, be applicable to commercial sales counter or family expenses, and energy consumption is very low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1, a kind of system that adopts the vacuum mode cooling quick-freezing food, be characterized in that it is made up of vacuum chamber 1, refrigeration system 2, vavuum pump 3, cold-trap 4, bowl cover 5, sealing ring 6, cup jar 7, triple valve 11 etc., bowl cover 5 covers the top at cup jar 7, there is sealing ring 6 centre, triple valve 11 links to each other with cup jar 7 by pipeline, and one of triple valve 11 leads to atmosphere 10, and the other end links to each other with vacuum chamber 1 by pipeline, vacuum chamber 1 is built-in with cold-trap 4, and the low-temperature receiver of cold-trap 4 is from refrigeration system 2.
Specific implementation method of the present invention:
The cup 8 that fills raw-food material solution is placed in the cup jars 7, covers the lid 5 of cup jars 7, on the cup jars 7 breather line is arranged, link to each other with triple valve 11, of triple valve 11 communicates 10, other end connection vacuum chamber 1 with atmosphere.Triple valve 11 can manually be controlled, and also can control automatically, when triple valve 11 leads to vacuum chamber 1, cup jar 7 interior pressure reduce rapidly, and can reach the pairing saturation pressure of food 9 material solution temperature rapidly, at this moment, solution evaporation boiling, and heat release cooling form frost or slob.At this moment triple valve 11 can be switched to atmosphere 10 and be communicated with,, open the lid 5 of cup jars 7, be i.e. edible or in refrigerator, deposit promptly to cup jar 7 return-airs.With the gas of vavuum pump extracting vacuum chambers 13, make and keep certain vacuum in the vacuum chamber 1.Considering when liquid phase transition becomes gas phase to increase specific volume greatly, therefore cold-trap 4 can be set, and makes condensation vapor on cold-trap 4, can reduce rate of air sucked in required greatly like this.
