Abstract

A kind of food freshness-keeping box, by casing, hermatic door, the flame-out deoxidation device of automatic combustion, constitute with the heating auto-cooling high-pressure steam sterilization device, but food such as the various vegetables of long preservation, fruit, bright cold cuts egg have characteristics such as simple in structure, cheap, that access is easy to use.

Description

Food freshness-keeping box

The invention belongs to the food hygiene equipment technical field.Be a kind of with the sealing of microgravity combustion deoxidation automatic negative-pressure, fresh-keeping storage vegetables, fruit, the dual-purpose antistaling storing case of fruit, dish, delicatessen of delicatessens such as also salable heating high-pressure sterilization, cooling automatic seal storage fish, meat.

Existing food preservation technology, adopt substantially that refrigerator storage is fresh-keeping, anion generator is fresh-keeping, really, dish spraying chemical agent is fresh-keeping, with fresh-keeping, the packed method such as fresh-keeping of artificial air's environment cellar for storing things storage.The above two need frequent consume electric power and cost higher.The fresh-keeping troublesome poeration of chemical agent coating must additionally thoroughly clean simultaneously.Storage fresh-keeping and packed fresh-keeping neither can often getting repeatedly in artificial air's environment cellar for storing things deposited.At any time can take and food fresh keeping storage bin easy and simple to handle is the food storage equipment that broad masses press for.

Purpose of the present invention is simple in structure in order to create, and without electric power energy, can realize the fruit freshness preserving storage tank and produce the ultimate food antistaling storing case of the can effect alive of repeated use continuously with shirtsleeve operation.

Concrete structure of the present invention and principle of work, accompanying drawings is as follows:

Accompanying drawing 1 is the food freshness-keeping box constructional drawing.

Accompanying drawing 2 puts out combustion deoxidizing and high voltage sterilizing device cutaway view certainly for spontaneous combustion.

Accompanying drawing 3 is interior pressure telltale and contact ventilative needle-valve scheme drawing.

Concrete structure of the present invention by the side with the positive square closed box (2) with garden shape inner gate-stop (3) of button post (1), there is interior pressure to show film (8) and vent valve reed (7) in sponge rubber garden ring (6) the unit ring of inner face with surface-closed, two nipple posts (10) are arranged at the bottom, there is the interior pressure display (19) that sees accompanying drawing 3 outside and contacts the needle-valve (20) of breathing freely, there is tension hook (9) side, be connected in square external door (5) on the casing with folding, dividing plate (4) is arranged in the casing from top to bottom, steam generator (12), the automatic combustion of seeing accompanying drawing 2 alcolhol burner (17) that goes out The open end of automatic ignition device (11), closed box (2) bottom that drives rolling flint wheel (16) with automatic rack (15) every (14), wherein have from put out kerosene stove (13), around passing to steam generator (12) glue pipe socket air nozzle formula high pressure gas bleeder valve (18) formation that sees accompanying drawing 2 on every side from putting out kerosene stove combustion core annular spread. During use, as be the fresh-keeping storage fruit and vegetable, fruit or vegetables can be placed on the dividing plate (4), shut then square external door (5), tension hook (9) is hung over upper, the compression of button post (1). At this moment, the nipple post (10) of square external door (5) inner face bottom just automatically inwardly pushing tow with the topped sparking tooth bar (15) of sealed film, drive rolling flint wheel (16), the flint bar sparking in the frictional sparking device (11) is lighted two spontaneous combustions from putting out alcolhol burner (11). Therefore square external door (5) is closed the time, and sponge rubber unit's ring (6) has sealed again unit's door (3) in the casing, and the case inner air and outer air can not be exchanged circulation substantially, and spontaneous combustion exhausts just automatic distinguishing from putting out alcolhol burner (17) with the oxygen combustion in the casing. The result of casing internal combustion deoxidation causes negative pressure in the casing, will nuzzle most of suck in unit's door (3) of sponge rubber unit's ring (6) of unit's door (3) and can not become flexible easily or deviate from and seal. The interior AIR Proportional of seal case this moment is nitrogen 92～97% substantially. Carbon dioxide 2～5%, chlorine 1～3% are the fresh-keeping optimal gas state of air. At this moment, the interior pressure indicator (19) of the top, positive outside of square external door (5) illustrates the negative-pressure sealing state that is in because negative pressure in the case inside contracts. As open chamber door and take food product, can hold in both hands the ventilative needle-valve (20) of pressing indicator (19) top in the extruding with first iron nail or other thin unit earlier, negative pressure in then the air of outside enters and removes in the casing, pulling tension hook (9) handle is just can open door. With after again door is shut, automatic deoxidation negative-pressure sealing again is without special operational.

If storage fish, cooked meat product, need autoclaving sterilization after sealing preserve, run after fame and pay in fact " can alive ". At this moment, earlier food is put on the case internal partition. In steam generator (12), fill with water afterwards, shut square external door (5), the deoxidation negative pressure takes place in the case. Light then certainly the put out kerosene stove (13) of the open end in (14) and shut opening End partition door just operation is over.

Make at the bottom of by veneer case in the case steam generator at the end (12) water that is heated in the vessel boil gradually and rise And and produce high pressure steam from putting out kerosene stove.Because of casing is basic sealing state, in the casing high-pressure sterilizing course.After reaching the autoclaving purpose, vapour pressure continues to increase, then high pressure steam by case at the bottom of steam generator (12) glue pipe socket gas on every side chew formula aie escape valve (safety valve) (18) ejection.Because of the nozzle annular is fired core towards kerosene stove (13), so the steam of ejection extinguishes kerosene stove (13) automatically.With extinguishing of kerosene stove (13), temperature progressively descends naturally in the casing, and the water vapour cooling is reduced to water, is negative pressure in the casing again, and interior unit door sucks sponge rubber unit's ring (6) again and forms depth seals.At this moment the food fresh keeping hutch has become the alive can the same with the operating procedure of reality processing can on the spot with regard to name Fu Qi.Food can long preservation, and the time spent repeats once to open the door, close the door again, lights the such shirtsleeve operation of kerosene stove and has just finished manufacturing again of can alive.The present invention will will produce the huge social benefit to people's hygiene and health, economize on electricity, the waste of saving food spoilage for food processing factory, catering industry, resident family bring huge economic benefit.
