Tunnel sterilizer

Affiliated technical field

The present invention relates to a kind of edible fungus culturing substrate sterilizing installation.

Background technology

At present, general edible fungus culturing substrate sterilizing installation is divided into autoclaving equipment and normal-pressure sterilization equipment, and autoclaving equipment or capacity are too little or cost an arm and a leg, be used for small-scale production such as bacterium culture medium sterilization, the general normal-pressure sterilization equipment that uses of sterilization in enormous quantities more.Current, the domestic sterilizing edible fungus at normal atmosphere equipment major part of using is to be fit to medium-scale following production as normal pressure soil kitchen range, its defective, and the excessive steam conduction of capacity is inhomogeneous, and it is not thorough to sterilize, and the effect instability, and operation labor intensity is big; Indivedual big factories use the large box type normal pressure kitchen range of fuel oil or coal-burning boiler steam supply, and its defective is the hardware and software cost height of boiler, administer and maintain complexity, and energy consumption is big.

Summary of the invention

At the existing defective of existing sterilizing installation, the objective of the invention is to utilize the GEOTHERMAL WATER resource, a kind of energy-conservation, easy and simple to handle, sterilization tunnel sterilizer that quantity is big, production efficiency is high is provided.

The technical solution adopted for the present invention to solve the technical problems is: a kind of tunnel sterilizer, comprise heating arrangements, the sterile chamber, heating arrangements is positioned at the below of sterile chamber, the two ends, sterile chamber respectively are provided with a Room door, heating arrangements top is provided with a conveying mechanism that runs through two Room doors, and the sterile chamber is long shape body, and sterile chamber's wall body adopts the multiple structure of stainless steel layer, rock wool layer, polystyrene layer, color steel layer from inside to outside.

Described heating arrangements comprises heating kettle, be positioned at the combustor of heating kettle, be connected with combustor be the staggered heat-exchange tube in two-way two-layer position, the heat-exchange tube other end is connected in smoke collection pipe.

The invention has the beneficial effects as follows: geothermal energy can combine with oil plant, cooperate multiple insulation construction, energy-saving effect is obvious, the heat energy of heating arrangements directly transmits, improve the thermal efficiency, the design of tunnel type and sterile chamber adopt two-door structure to cooperate conveying mechanism, and be simple to operation, the production efficiency height, amount of sterilization is big.

Specific embodiment one

As shown in the figure, tunnel sterilizer of the present invention, comprise heating arrangements, sterile chamber 1, heating arrangements is positioned at the below of sterile chamber 1, comprise heating kettle 8, be positioned at the combustor 4 of heating kettle 8, the combustor 9 that links to each other with combustor 4, heating kettle 8 are connected with combustor 4 is the staggered heat-exchange tube 17 in two-way two-layer position, heat-exchange tube 17 other ends are connected in smoke collection pipe 18; Sterile chamber 1 is long shape body, and two side lower parts are provided with many exhausting cold air pipes 5, and 1 two ends, sterile chamber respectively are provided with a Room door 2, and sterile chamber's 1 wall body adopts the multiple structure of stainless steel layer 22, rock wool layer 23, polystyrene layer 24, color steel layer 25 from inside to outside; Be provided with the conveying mechanism of a detachable installation between sterile chamber 1 and the heating arrangements, comprise above the heating kettle 8 through the guide rail 3 of two Room doors 2 and the pillow ferrum 19 between the guide rail 3.

During use, heating arrangements is placed in underground, be provided with rock wool interlayer 26 between the heating kettle 8 of heating arrangements and the brick foundation 16 on land, be provided with the step 32 that reaches the usefulness that falls for the inspection-pit 31 of maintenance usefulness in combustor 9 outsides, cooperate water level control box 10 to be delivered into heating kettle 8 by underground heat water pipe 12 GEOTHERMAL WATER, the spout 15 that adopts the two shower nozzle Light Oil Burning Machine 9 of 300,000 kilocalories is to combustor 4 heating, combustor 4 and heat-exchange tube 17 are given GEOTHERMAL WATER in the heating kettle 8 with thermal energy transfer, make GEOTHERMAL WATER be warming up to generation steam, the smoke collection pipe 18 that the flue gas elder generation process that produces during heating is connected with heat-exchange tube 17 is after smoke exhaust pipe 29 is discharged, and the steam of generation can be sterilized to the material of luggage carrier 27 on the guide rail 3 in the sterile chamber 1.

The present invention can be in conjunction with being used for steam sterilization with geothermal energy and oil firing, make the inner surface of sterile chamber with rustless steel, prevent the corrosion of the GEOTHERMAL WATER that sulfur content is high, with the central chamber that directly contacts with GEOTHERMAL WATER, staggered heat-exchange tube and the two-way mode of compiling smoke evacuation in two-way two-layer position, improve the thermal efficiency; Big at GEOTHERMAL WATER hardness, easy incrusted characteristics are undertaken material and are moved with the guide rail of load-bearing and adopt demountable structure, by the drain pipe that is positioned under the heating kettle water of pot are discharged, and are convenient to the cleaning of lower heating pot; Sterile chamber's wall body adopts four layers of composite construction of steel skeleton, from inside to outside, corrosion resistant plate plays anticorrosion, antiseep, anti-malleation expansion, rock wool layer both can tolerate the high temperature of degree more than 100, played heat-blocking action again, the material that it is the heat-proof quality height that the polystyrene bubble is moulded, cost is low, can reduce the thickness of heat-insulation layer, because the stopping of rock wool layer, this layer can Yin Gaowen and be out of shape, and outer color steel plays fastening, rust inhibition; Adopt asymmetric double shower nozzle combustor,, shorten boiling time, select single shower nozzle operation, save the energy at holding stage at the heating period standard-sized sheet; Row's cold-air duct is offered in segmentation, arranges coldly to shorten sterilization time evenly, fast, saves the energy; Luggage carrier can be from the sterile chamber one end the chamber door so that go out from another chamber door, the material car load advances car load and goes out, and reduces labor intensity greatly; The sterile chamber can adopt unidirectional pair of door leaf structure, make between the very big system of dustiness hired car with the demanding seed receiving vehicle of cleanliness factor between ingenious the connection and isolation, the tunnel type design can increase and decrease the design capacity of sterile chamber as required, is very beneficial for edible fungus industrial production.
