Description

Technical Field

[0001] The utility model belongs to the technical field of edible fungus production, and in particular relates to an edible fungus liquid fermentation tank with good fermentation effect. Background Art

[0002] In food processing, liquid culture fermentation tanks use the principle of biological fermentation to provide the bacteria with the nutrients, pH, temperature and oxygen required for growth, thereby creating an optimal growth environment for the bacteria, allowing the bacteria to grow rapidly and multiply rapidly. Lactobacillus plantarum, lactic acid bacteria, yeast, bifidobacterium, thermophilic Streptococcus, Bacillus coagulans and Lactobacillus acidophilus are all liquid cultures that are soluble in water.

[0003] The liquid strain fermentation process is to add the strain into the fermentation tank, maintain a constant temperature in the fermentation tank through a heating device, and stir it regularly to keep the strain, nutrients, pH, temperature and oxygen content in the liquid environment of the fermentation tank uniform until the fermentation is completed. In actual use, the strain inside the fermentation tank may heat up during the fermentation process, causing the temperature inside to be unsuitable for the subsequent fermentation of the strain. After the temperature inside the fermentation tank rises, it is not convenient to cool it down. Generally, the jacket of the fermentation tank is cooled, and then an agitator is set to improve the heat transfer efficiency. This method cannot quickly and evenly reduce the temperature of the material due to the small contact area between the material and the tank wall, which affects the quality of the fermentation liquid. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a liquid fermentation tank for edible fungi with good fermentation effect, so as to solve the problem that the existing method of cooling the fermentation liquid using a jacket in combination with an agitator cannot quickly and evenly reduce the temperature of the material, thereby affecting the quality of the fermentation liquid.

[0005] To achieve the above objectives, the utility model adopts the following technical solution: a liquid fermentation tank for edible fungi with good fermentation effect, comprising a fermentation tank body, an agitator installed on the fermentation tank body, an inner support plate installed on the lower side of the fermentation tank body, a lower water collecting pipe supported and installed on the inner support plate, a plurality of built-in heat exchange components are arranged on the lower water collecting pipe, the built-in heat exchange components comprise an inner tube body and an outer tube body sleeved on the outer side of the inner tube body, the lower water collecting pipe connects a water inlet pipe and the outer tube body, the bottom end of the inner tube body passes through the bottom of the lower water collecting pipe, the top end of the inner tube body passes through the bottom of the upper water collecting pipe, the upper water collecting pipe connects a water outlet pipe and the outer tube body, and the water outlet pipe and the water inlet pipe are connected by a cold water pipeline.

[0006] The beneficial effect of the utility model is that when the agitator rotates, the material at the bottom of the fermentation tank body flows upward, and then the material enters the multiple inner tubes, and fully exchanges heat with the cold water flowing between the outer tube body and the inner tube body, thereby effectively improving the cooling efficiency of the fermented material and improving the fermentation quality.

[0007] In order to enable the material to flow effectively from bottom to top in the built-in heat exchange component;

[0008] As a further improvement of the above technical solution: the agitator is a folding blade agitator, and the agitator blades of the agitator are located below the built-in heat exchange component.

[0009] The beneficial effect of this improvement is that when the agitator rotates, the material close to the axis of the agitator moves downward, and the material away from the axis of the agitator moves upward. In the process of the material flowing upward, it enters the inner tube body through the bottom end of the inner tube body, flows from top to bottom to the top of the inner tube body and then enters the fermentation tank body to realize circulation flow.

[0010] In order to enable the material to flow effectively from bottom to top in the built-in heat exchange component;

[0011] As a further improvement of the above technical solution: the inner support plate is an annular plate structure, and the inner support plate is welded to the inner wall of the fermentation tank body.

[0012] The beneficial effect of this improvement is that the inner support plate can block the upwardly flowing material, so that the material flowing upward along the inner wall of the fermentation tank enters the inner tube body, thereby achieving effective circulation flow.

[0013] In order to ensure the uniformity of cooling of fermented materials;

[0014] As a further improvement of the above technical solution: multiple built-in heat exchange components are circumferentially arranged around the axis of the fermentation tank body and the agitator, the lower water collecting pipe and the upper water collecting pipe are both annular pipe structures, and the axes of the lower water collecting pipe and the upper water collecting pipe are collinear with the axes of the fermentation tank body and the agitator.

[0015] The beneficial effect of this improvement is that the material can be evenly distributed and flow into multiple built-in heat exchange components, and efficient heat exchange is achieved during the flow in the built-in heat exchange components.

[0016] In order to ensure the uniformity of cooling of fermented materials;

[0017] As a further improvement of the above technical solution: the inner tube body and the outer tube body are both circular tube structures, and the axes of the inner tube body and the outer tube body are collinear.

[0018] The beneficial effect of this improvement is that during the flow of material inside the inner tube body, the cold water flowing between the annular cavity formed between the inner tube body and the outer tube body can effectively reduce the temperature of the inner tube body, thereby achieving uniform cooling of the material inside the inner tube body.

[0019] In order to ensure the stability and sealing of the connection between the built-in heat exchange component and the lower and upper water collecting pipes;

[0020] As a further improvement of the above technical solution: the two ends of the inner tube body are welded to the top of the upper water collecting pipe and the bottom of the lower water collecting pipe, and the two ends of the outer tube body are welded to the top of the lower water collecting pipe and the bottom of the upper water collecting pipe.

[0021] The beneficial effect of this improvement is that the welding connection method can effectively ensure the stability and sealing of the connection between the built-in heat exchange component and the lower water collecting pipe and the upper water collecting pipe, so that the device can be used safely for a long time and stably.

[0022] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
