Description
Technical field
The utility model relates to fruits and vegetables cooling device field, is a kind of fruits and vegetables vacuum pre-cooling machine specifically.
Background technology
Vacuum freezing is a kind of desirable preserving fruit and vegetable utilizing preconditioning technique, it is a fastest Refrigeration Technique of present cooling rate, and it is fast to have cooling velocity, and cooling effect is even, so numerous advantages such as cleanliness without any pollution are the precooling link in the fresh-keeping chain that therefore is widely used.It can eliminate physiological activity and biochemical variations such as its field heat, reduction respiratory intensity in vegetables, fruit and flowers are gathered the back very first time, make agricultural product evenly cooling rapidly after harvesting, reduce and the inhibition microorganism, kill pests, reduce the rotting rate of agricultural product greatly, and can prevent its a large amount of dehydrations, and keep color and the nutritional labeling of existing product, prolong storage period.This technology is at agricultural product such as vegetables, fruit and fresh flower and cure class, and numerous food processing such as prepared food field has obtained using widely.
The fruits and vegetables vacuum pre-cooling machine of prior art comprises: storage tank, water vapour coagulator, baffle-box, circulating pump, refrigeration system, No. two circulating pumps, cooling tower, one-level vavuum pump, No. two one-level vavuum pumps, two-stage vacuum pump and steam-water separators etc., the structure more complicated, contain many vavuum pumps, power consumption is bigger during operation, and the long-play vavuum pump damages easily, can't continue to produce.
The utility model content
The purpose of this utility model is the problem that exists at prior art, provide a kind of simple in structure, power consumption is little, the fruits and vegetables vacuum pre-cooling machine of long service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of fruits and vegetables vacuum pre-cooling machine, comprise storage tank, be connected in the water vessel of storage tank, be connected with vavuum pump on the described water vessel, described storage tank is provided with automatic controller, be equipped with valve between described water vessel and vavuum pump, the compressor, be provided with condenser in the described water vessel, described condenser links to each other with the compressor that is arranged at the water vessel outside, and described vavuum pump comprises rapid vacuumizing pump and the holding vacuum pump that is connected in side by side on the water vessel; Described automatic controller is provided with the temperature measuring head that stretches in the storage tank, and described compressor, rapid vacuumizing pump, holding vacuum pump and valve all electricly connect with automatic controller.
Further: described water vessel is provided with Pressure gauge.
Further: described water vessel bottom is provided with drainpipe.
Further: described water vessel is connected by anti-negative pressure pipe with described storage tank.
Further: described rapid vacuumizing pump is Roots vaccum pump, and described holding vacuum pump is rotary-vane vaccum pump.
Useful technique effect of the present utility model is:
(1), in the technical solution of the utility model link to each other with compressor then because directly in water vessel inside condenser is set, water vessel is connected with vavuum pump again, can realize fast fruits and vegetables being carried out vacuum pre-cooling, the convenient use simple in structure.
(2), in the technical solutions of the utility model, because two vavuum pumps are only arranged, start earlier during work and close the fast vacuum pump after the rapid vacuumizing pump is evacuated down to predetermined pressure, open holding vacuum pump again, this process vavuum pump alternate run, can effectively reduce the energy consumption that all vavuum pumps move simultaneously, and be conducive to prolong the service life of vavuum pump.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As a kind of fruits and vegetables vacuum pre-cooling of Fig. 1 machine, comprise storage tank 1, be connected in the water vessel 2 of storage tank 1, be connected with vavuum pump on the water vessel 2, storage tank 1 is provided with automatic controller 9, between water vessel 2 and the vavuum pump, be equipped with valve 11 between water vessel 2 and the compressor 4, be provided with condenser 3 in the water vessel 2, condenser 3 links to each other with the compressor 4 that is arranged at water vessel 2 outsides, vavuum pump comprises rapid vacuumizing pump 5 and the holding vacuum pump 6 that is connected in side by side on the water vessel 2, rapid vacuumizing pump 5 is Roots vaccum pump, can realize that to storage tank 1 rapid vacuumizing, holding vacuum pump 6 is rotary-vane vaccum pump, can realize that storage tank 1 maintains in a certain vacuum pressure scope; Automatic controller 9 is provided with the temperature measuring head 10 that stretches in the storage tank 1, and temperature measuring head 10 can feed back to automatic controller 9 with the fruits and vegetables internal temperature at any time; Compressor 4, rapid vacuumizing pump 5, holding vacuum pump 6 and valve 11 all electricly connect with automatic controller 9; Water vessel 2 is provided with Pressure gauge 7, and the pressure in the monitoring process at any time changes, and can change the automatic control that realizes equipment working state by pressure; Water vessel 2 bottoms are provided with drainpipe 8, can be used for discharging the aqueous water through condenser 3 coolings; Water vessel 2 is connected by anti-negative pressure pipe with described storage tank 1, can improve production security.The utlity model has simple in structurely, the little convenient characteristics of using that consume energy can be extensive use of in actual production.
