Simple sterilizing method for long bacteria stick

Abstract

The invention discloses a simple sterilizing method for a long bacteria stick. The method comprises making of the bacteria stick, simple sterilization, inoculation and cultivation, and fruiting management. The simple sterilization of the long bacteria stick comprises sterilizing equipment and a sterilizing method, wherein the sterilizing equipment comprises a normal-pressure steam boiler and a sterilizing pile; the sterilizing pile comprises an air inlet pipeline, a sterilizing frame, an induction thermometer, an air exhaust pipe, a sealing layer, a heat-preserving stress layer and a blank pressing sand bag; the sterilizing method comprises bacteria stick loading, covering of the sealing layer and the heat-preserving stress layer, blank pressing, heating, heat preservation, fire ceasing, and cooling of a fruiting stick. By adopting the method, heat exchange between hot steam and the bacteria stick can be accelerated, the bacteria stick piling difficulty is lowered, deformation of the bacteria stick is effectively prevented, damp and hot sterilization can be ensured, the sterilizing effect is enhanced, and the formation of sterilization dead corners is prevented. Meanwhile, an accurate sterilization timing point can be introduced, the difficulty in determining the sterilizing time is lowered, and energy can be saved effectively.

Description

technical field [0001] The invention belongs to the field of light and simplified cultivation of edible fungi, and in particular relates to a light and simplified sterilization method for long mushroom sticks. Background technique [0002] Long mushroom sticks refer to mushroom sticks made of 15-17×55-60cm plastic bags, which are currently widely used in the cultivation of shiitake mushrooms, fungus and other varieties. [0003] The sterilization method of edible mushroom sticks (packages) has been continuously improved with the advancement of edible fungus cultivation technology in my country. It has successively experienced soil steaming stoves made of bricks and cement, atmospheric pressure steel plate sterilization stoves, boat-shaped sterilization stoves, and high-pressure sterilization cabinets. High-pressure sterilization cabinets are suitable for factory production, with high prices and large profits. They have developed rapidly in recent years, and their equipment an...

Problems solved by technology

[0003] The sterilization method of edible mushroom sticks (packages) has been continuously improved with the advancement of edible fungus cultivation technology in my country. It has successively experienced soil steaming stoves made of bricks and cement, atmospheric pressure steel plate sterilization stoves, boat-shaped sterilization stoves, and high-pressure sterilization cabinets. High-pressure sterilization cabinets are suitable for factory production, with high prices and large profits. They have developed rapidly in recent years, and their equipment and processes have obtained many patents. At present, the light and simplified cultivation mode is still the main method. The bacteria sticks for cultivation are mainly long bacteria sticks, and the sterilization methods are mainly soil steam stoves made of bricks and cement, atmospheric pressure steel plate sterilization stoves, and boat-shaped sterilizers. Bacterial foci, the size of the sterilizing foci, the method of placing the bacteria rods, and the sterilization time are very different from region to region. There are also great differences between households and bases in the same area. It is very difficult for mushroom farmers to master

[0004] At this stage, the earth steaming stoves, atmospheric steel plate sterilization stoves, boat-shaped sterilization stoves and the improved models of these stoves used in the production of shiitake mushrooms and fungus have not solved the problem of the timing point of sterilization; The stacking between rows is tight, and even the cross-stacking of "ten" shapes between layers. These changes further increase the difficulty of ventilation in the sterilization pile, and have not fundamentally solved the problem of bacterial sticks falling sideways during stacking, and " The cross-stacking in the shape of "ten" is also easy to cause the deformation of the bacterial rods and increase the rate of inoculation contamination; for better airtightness when these stoves are built, special air exhaust devices are generally not built, and the sterilization process does not have an active air exhaust process. As a result, it is easy to form dry heat sterilization, resulting in dead ends for sterilization; the boat-shaped sterilization stove only uses a layer of plastic film sealing layer, and rarely covers it with a layer of tarpaulin as a bearing layer. Without a heat insulation layer, it will cause energy waste

[0005] In recent years, during the cultivation process of shiitake mushrooms and fungus, due to the wrong timing point of sterilization, the sterilization is not complete, the heating time is too long, which leads to the acidification of the compost, the sterilization pile of bacteria sticks is too large and the heat conduction is poor, which leads to the center becoming a sterilization center. Dead corners, improper stacking of mushroom sticks and excessive stacking lead to deformation of the mushroom sticks, resulting in a decrease in the rate of inoculation of genuine products, etc., which have brought great losses to mushroom farmers, and even led to bankruptcy of some bases

[0006] In short, the current soil steam stoves, atmospheric pressure steel plate sterilization stoves, boat-shaped sterilization stoves, etc. all have poor air permeability between the bacteria rods, high difficulty in stacking bacteria rods, and difficulty in forming a real moist heat sterilization, etc. question

[0007] The equipment cost of the present invention is much lower than that of the high-pressure sterilizer, and it solves the inaccurate timing points of the existing sterilization method, easy dumping of the sterilized pile when stacked, poor ventilation, easy formation of sterilizing dead angle, and long heating time The problems such as the acidification of the culture material caused by it are a kind of long-term stick sterilization method suitable for light and simplified cultivation of shiitake mushrooms and fungus, and it is an effective substitute for the existing long-term stick sterilization method.
