Abstract

A cyclic heating steamer belongs to a novel energy saving and emission reduction technology and a novel product, and is characterized in that a heating ring is connected to the outer bottom of the conventional steamer, the heating ring is encircled by a metal pipe with good thermal conductivity, the inner end of the heating ring penetrates the center of the steamer bottom and extends into the steamer, and the outer end of the heating ring penetrates through the steamer through the steamer bottom edge. During food steaming, the heating area of the steamer bottom can be increased greatly, and the water in the steamer is heated circularly from low temperature to high temperature, thereby saving fuel and the food steaming time obviously. At the same time, the carbon dioxide emission is reduced evidently, and the cyclic heating steamer is conductive to the reduction of the atmospheric greenhouse effect, and has simple manufacture process, low cost, large application and considerable social benefit and economic benefit.

Description

Circulation heating steamer

Technical field: the invention belongs to energy-saving and emission-reduction, reduce new technology, the new product of greenhouse effects.

Background technology: traditional steamer heating principle is: at the bottom of the hot heating kettle that fuel combustion produces, the bottom of a pan is the cold water in the heating kettle again.Because of the bottom of a pan area of traditional steamer is little, so rate of heat exchange is low, a lot of heats are run away, and therefore waste fuel.

Summary of the invention: key problem in technology of the present invention has two: the first connects a heating collar of being made by metal tube with the outer the bottom of a pan of traditional steamer, and this encloses stereo heating, and its surface area increases nearly 3 times, and rate of heat exchange is apparently higher than traditional steamer.Its two be traditional steamer the bottom of a pan layer water be heated to rise in the back and in, the upper strata mixes, so three layers of water temperature are almost equal.And this energy-conservation pot to be heating collar water heating back pushed up the superiors in the pot, the upper strata than in, lower floor's water temperature is much higher, is that the coldest water enters heating collar and carries out heat exchange so always, it is much higher obviously to carry out the efficient of heat exchange than the mixed warm water of traditional steamer.Therefore circulation heating steamer is energy-conservation obviously.

Description of drawings: the present invention is further described below in conjunction with accompanying drawing.Fig. 1 is traditional flat steamer, and Fig. 2 is a steamer (A type) at the bottom of the circulation heated flat; Fig. 3 is a steamer at the bottom of the traditional round, and Fig. 4 is a circulation heating round bottom steamer (Type B).

(B) among the figure is the bottom of a pan section of heating collar; (A) be the water inlet of heating collar; (C) be the pot inner segment of heating collar; (D) be the delivery port of heating collar. (E) be boiler grate; (F) be pot lid handle. The water of (B) section is heated at first during the steamed wheaten foods thing, and rises along (C) section, returns into pot the superiors of interior water from pipe end (D), and the cold water in the bottom of a pan enters in (B) section from water inlet (A) again simultaneously. Move in circles like this, the water contact flame that always temperature is minimum in the pot is heated. Because the temperature difference of water in flame and the heating collar is big, so the rate of heat exchange height is fuel saving. Steamer with heating collar increases than the traditional steamer endotherm area that does not have heating collar, so increase heat absorption, fuel saving. Therefore cyclic heating steamer is more obvious than traditional steamer fuel saving.

The specific embodiment: select two shapes, the identical flat steamer of volume (one with heating collar) and two shapes, the identical round bottom steamer of volume (having heating collar for), in the steamed bun that steams same quantity on the same far infrared gas range (pot amount of water, initial water temperature identical) record consumption coal gas amount and used time when steamed bun cooks, find that A, Type B steamer are than corresponding traditional steamer saving coal gas with save time and be about 33%--40%.

Claims (2)

1. circulation heating steamer is characterized in that it is made up of with the heating collar that is connected with its outer the bottom of a pan, pot double-edged fine-toothed comb and pot lid handle common traditional steamer of different shape, and wherein heating collar is made by metal tube, and this heating collar comprises; Be positioned at the bottom of a pan section in the outer the bottom of a pan of steamer, water inlet, pot inner segment and delivery port.

2. by the said steamer of claim 1, it is characterized in that; Can be flat or round bottom at the bottom of this steamer.
