Description

Spiral food heating equipment

Technical field

The present invention relates to the field of food processing, especially a kind of spiral food heating equipment.

Background technology

Digesting apparatus in the early stage food-processing industry has cooking-pot type, boiling vessel such as box, and the disadvantage of these equipment is to produce continuously, and labour intensity hand-manipulated is big, production capacity is low, and easy and Food Contact cause the food finished product unhygienic, the product quality instability; Box digesting apparatus needs several special people to insert dish, lower wall, come out of the stove, go into stove, opening fire door will wait the interior steam of stove just can come out of the stove after some less at every turn, close upper furnace door and heat up again again, wasted a lot of times and steam, so its production cost height, power consumption are big; The precooker that a kind of tunnel type is arranged is at present produced this shortcoming continuously though it has solved, and this tunnel type precooker floor space is big, and energy dissipation is big, production efficiency is lower.

Summary of the invention

The purpose of this invention is to provide a kind ofly can produce continuously, homogeneous heating, save again that the energy, floor space are few, health, spiral food heating equipment that production efficiency is high.

For solving the problems of the technologies described above, spiral food heating equipment of the present invention comprises helical mount in the storehouse body, storehouse body and the conveyer belt on the helical mount, described storehouse body is provided with pressure limiting device, and described storehouse external body is provided with control device, is characterized in also being provided with on the helical mount heater.

Described heater is made of radiation heating tube and steam pipe.

Described heater is made of heating wire and steam pipe, heating wire and steam pipe be arranged on conveyer belt below.

Described radiation heating tube is arranged on the helical mount, be connected by bridge piece between radiation heating tube inlet and the radiation heating tube, layer with layer radiation heating tube between also be connected by bridge piece.

Described bridge piece is U type or circular arc.

Described helical mount is even numbers.

The present invention has the following advantages compared with prior art:

1, adopt helical mount to be provided with conveyer belt, changed the situation that the product fixed point of traditional box precooker is put, the route of all product processes is the same, the product heating degree is the same, this makes product finish maturing process under the state of the best with regard to the excessive situation of slaking not yet done, that have that the product that has changed box precooker has, and product sensory and special mouthfeel are good, improve the quality of product, also improved the yield of finished product; Utilized the space fully, nearly 300 meters long conveyer belts only need take up an area of tens meters long device locations, according to the floor space of having saved equipment greatly than tunnel type precooker, have reduced the land area of factory, have also saved the investment on factory building; Simultaneously also lost much smaller with respect to tunnel type precooker energy of spiral conveyer belt plays the effect of the saving energy; Conveyer belt transmits, reduced the chance that product is polluted, be more conducive to consumer's health, because product is after entering the slaking of spiral precooker, until enter next machine, need not artificial linking, changed the with serious pollution problem of box digesting apparatus, stopped the product secondary pollution problem, made consumers in general's health obtain sufficient assurance.

2, adopt the storehouse body structure, vapours is positioned at machine top after rising, and top seals, and heat-energy losses is few.

3, heater is made of screw type radiation heating tube and steam pipe, utilized the fuel factor of steam fully, accelerated the slaking speed of product, promptly reached purpose of energy saving, also reduced the discharging that boiler combustion is polluted, the indirect purpose that has reached the raising environmental protection, and radiant heating device is very energy-conservation.

4, described radiation heating tube is arranged on the helical mount, be connected by bridge piece between radiation heating tube inlet and the radiation heating tube, the layer with layer radiation heating tube between also be connected by bridge piece, adopt plate-like to arrange radiation heating tube, make same horizontal level be heated evenly, adopt bridge piece to connect simultaneously, bridge piece plays the terminal effect, makes the spiral radiation heating tube to be installed conveniently.

5, adopt the double helix supporting structure, conveyer belt double helix trend can realize that hanging down into of product hang down, and is convenient to production operation.
