Description

Technical Field

[0001] The utility model relates to a shiitake mushroom stick sterilizing device, belonging to the technical field of edible mushroom processing. Background Art

[0002] China is rich in mushroom resources and is one of the earliest countries to cultivate and utilize mushrooms. Mushrooms are not only delicious but also nutritious, and are often called healthy food. At present, mushroom cultivation is very popular. Generally, artificial mushroom cultivation involves the sterilization technology of mushroom sticks. Sterilization is also an important link in the quality of mushroom production. Mushroom sticks need to be sterilized during production. Most of the existing sterilization steam furnaces directly stack the mushroom sticks and place them in the sterilization pot, and the bottom is in direct contact with the pot body. On the one hand, it is not conducive to steam permeability. On the other hand, the sterilization effect is not good, the time is long, and steam is wasted, and effective energy conservation and emission reduction cannot be achieved. On the other hand, the mushroom sticks are in direct contact with the pot body, and the stacked mushroom sticks are prone to produce water and some debris, thereby contaminating the mushroom sticks and affecting the output of the mushroom sticks.

[0003] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a mushroom spawn sterilization device to make it more valuable for industrial use. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a mushroom spawn sterilizing device.

[0005] The utility model discloses a shiitake mushroom stick sterilizing device, comprising an outer sterilizing tank body and an inner sterilizing tank body arranged inside the outer sterilizing tank body, wherein the outer sterilizing tank body and the inner sterilizing tank body are respectively provided with material inlet and outlet windows and inner tank body material inlet and outlet windows correspondingly, which are used for feeding and discharging the mushroom sticks to be sterilized, a sterilizing steam inlet is arranged at the center of the bottom surface of the outer sterilizing tank body, a steam generating disk is arranged at the top of the sterilizing steam inlet, a plurality of steam generating holes are evenly arranged on the surface of the steam generating disk, the steam generating disk is directly opposite to the bottom opening of the sterilizing steam inlet, high-pressure steam is introduced from the sterilizing steam inlet, and the high-pressure steam is evenly introduced into the inner cavity of the inner sterilizing tank body through the steam generating holes, so as to perform high-pressure steam sterilization on the mushroom sticks to be sterilized; an ozone generator and a condensation controller are respectively arranged on the upper side walls of the outer sterilizing tank body and the inner sterilizing tank body, and a water outlet is also arranged at the bottom of the outer sterilizing tank body. The ozone generator can generate ozone in the inner cavity of the sterilization tank. Ozone can not only kill the miscellaneous bacteria in the tank, but also promote the growth of mycelium. The use of ozone as supplementary oxygen and to disinfect the mushroom sticks can significantly improve the mushroom yield. The condensation controller can lower the temperature of the inner sterilization tank so that the high-temperature steam contacts it after sterilization, condenses into water droplets, slides down the tank and flows out from the water outlet, thereby preventing excessive condensation water in the sterilization tank, affecting the quality of the mushroom sticks, and does not require manual cleaning of accumulated water.

[0006] Furthermore, the rotating mechanism includes a rotating motor installed on the top of the outer sterilization tank body, the bottom output end of the rotating motor is transmission-connected to a vertically arranged rotating shaft, a tray bracket is arranged in the middle of the rotating shaft, and a sterilization tray with a disc-shaped structure is fixedly installed on the upper surface of the tray bracket for placing the bacteria sticks to be sterilized; the use of a single-layer sterilization tray, on the one hand, effectively solves the problems of long sterilization time of the bacteria sticks and easy contamination by contact caused by stacking; on the other hand, it also makes the bacteria sticks easier to place and not easy to deform, and the moisture and debris in the steam sterilization are not easy to contaminate the bacteria sticks, thereby improving efficiency, saving time and reducing energy consumption.

[0007] Furthermore, the bottom end of the rotating shaft is also connected to a swirl paddle, which is used to stir and generate steam swirl, increase the contact area between steam and the mushroom sticks, and improve the sterilization effect;

[0008] Furthermore, the surface of the sterilization tray is evenly provided with a plurality of sterilization meshes, which are used for high-temperature and high-pressure steam to penetrate and fully contact the sterilized bacteria sticks, thereby improving the sterilization effect, and also allowing the water droplets after the steam condenses to drip and separate in time, thereby preventing excessive condensation from affecting the quality of the bacteria sticks;

[0009] Furthermore, a pressure relief port is provided on the top of the inner sterilization tank body to communicate with the outside. When the inner sterilization tank body is filled with sterilization steam and reaches a certain pressure, the pressure relief port is opened to release the pressure inside the tank body to prevent the damage of the mushroom stick caused by excessive pressure;

[0010] Furthermore, a plurality of steam condensation holes are evenly arranged on the surface of the lower half of the inner sterilization tank body, so that the condensed water droplets can flow out from the steam condensation holes and drip from the water outlet, thereby preventing excessive condensation water in the sterilization tank body from affecting the quality of the mushroom sticks, and no manual cleaning of the accumulated water is required.

[0011] By means of the above scheme, the present invention has at least the following advantages:

[0012] During the sterilization process, the sterilization device of the utility model drives the sterilization tray and the swirl paddle to rotate together, thereby stirring and generating steam swirl, increasing the contact area between the steam and the mushroom stick, and improving the sterilization effect; at the same time, the ozone generator can generate ozone in the inner cavity of the inner sterilization tank body, and the ozone can not only kill the miscellaneous bacteria in the tank body, but also promote the growth of mycelium. The use of ozone as supplementary oxygen and for sterilizing the mushroom sticks can significantly improve the mushroom yield rate; and the condensation controller can reduce the temperature of the inner sterilization tank body, so that the high-temperature steam contacts with it after sterilization, condenses into water droplets and slides down the tank body and flows out from the water outlet, thereby preventing the sterilization tank body from having too much condensed water, affecting the quality of the mushroom sticks, and there is no need to manually clean the accumulated water. When the inner sterilization tank body is filled with sterilization steam and reaches a certain pressure, the pressure relief port is opened to release the internal pressure of the tank body, so as to prevent the damage of the mushroom sticks caused by excessive pressure.
