Description

Technical Field

[0001] The present application relates to the technical field of edible fungus equipment, and in particular to a novel high-efficiency multi-unit warehouse for sterilizing bulk edible fungi. Background Art

[0002] The existing edible fungus bulk sterilization system of our company is a bulk sterilization output device composed of a sterilization bin, a cooling bin and a storage bin. Its structure consists of: sterilization system-cooling system-storage system-air compressor supply system-air filtration system-electrical control system;

[0003] The working process is as follows: the base material enters the sterilization chamber from the top feed port of the sterilization chamber (the augers in the chamber are in working state at this time). When the designed volume is reached (generally 80%), the feed port is closed and steam is introduced to start heating and sterilization. After about 30 minutes of temperature rise, the pressure in the chamber reaches 125°C and is maintained for about 120 minutes. The exhaust and pressure relief are started. When the pressure in the sterilization chamber is close to 0, the material is discharged to the cooling chamber.

[0004] When all the base materials in the sterilization chamber have entered the cooling chamber (the auger is in a state of continuous rotation and stirring during the discharge process), the top inlet of the discharge valve is closed, circulating water is introduced into the cooling chamber interlayer, the vacuum pump starts to evacuate, and the refrigerator starts to prepare for startup according to the program;

[0005] When the base material in the cooling bin drops to about 28°C, it starts to discharge into the storage bin. When all the base material in the cooling bin enters the storage bin, the discharge valve on the top of the storage bin is closed, and the two discharge valves (depending on the number or efficiency of bagging machines or multiple discharge ports) at the bottom of the storage bin are opened at the same time. The base material enters the base material bin of the bagging machine corresponding to the two discharge ports from the discharge barrel, and the process of loading sticks (bags) begins.

[0006] The above mixer-sterilization chamber-cooling chamber-storage chamber works in a reciprocating cycle to form a relatively efficient bulk material sterilization device.

[0007] Disadvantages of the three-level sterilization efficiency of traditional bulk sterilization equipment:

[0008] 1. The sterilization process of heating up the sterilization chamber is time-consuming, which is about three times the time taken by the existing cooling chamber. This leads to a serious mismatch between the sterilization efficiency of the sterilization chamber and the cooling efficiency of the cooling chamber, and cannot fully utilize the maximum utilization and efficiency improvement of the efficiency space generated by the design functional structure.

[0009] 2. After each base material enters the sterilization bin, steam is required to heat and sterilize it, and it is circulated daily, so there is no risk of pollution in the sterilization bin. However, the cooling bin and storage bin in the prior art are sterilized once at the start of daily production and used for multiple days. In order to avoid the continuous deterioration of the sterile environment in the cooling bin during continuous use, which may cause the base material to be contaminated by mold and lead to contamination of the cultured bacteria sticks (bags) after the base material is packaged, it is generally necessary to re-sterilize the cooling bin and storage bin once every 6-7 days, and the work must be stopped for one day during sterilization. The most direct impact of this solution is that the efficiency is significantly affected. Even if it is sterilized once every 6-7 days, it is impossible to completely guarantee the complete sterility of the base material during this period. Therefore, the existing bulk material sterilization has obvious dual design defects in efficiency and effect, and needs to be improved. Utility Model Content

[0010] The technical problem to be solved by the present application is to provide a new type of efficient multi-unit sterilization chamber for bulk edible fungi, which improves the sterilization efficiency by configuring the number of cooling chambers and sterilization chambers, and at the same time improves the working environment during cooling, so as to ensure that the chamber is in a sterile state as much as possible during cooling to avoid contamination.

[0011] In order to solve the above technical problems, the technical solution adopted in this application is:

[0012] A novel edible fungus bulk sterilization high-efficiency multi-linked warehouse includes a plurality of sterilization cooling cache multifunctional integrated warehouses arranged in parallel and a storage warehouse connected to the sterilization cooling cache multifunctional integrated warehouse; the number of the storage warehouses is generally two, and each storage warehouse is connected to each of the sterilization cooling cache multifunctional integrated warehouses. The sterilization time of the sterilization cooling cache multifunctional integrated warehouse is t1, the cooling time of the sterilization cooling cache multifunctional integrated warehouse is t2, and the number n of the sterilization cooling cache multifunctional integrated warehouse is t1 / t2, taking an integer, for example, t1 / t2=2.5, then n is 3.

[0013] Furthermore, the storage bin includes a storage tank body and an augers installed in the storage tank body, the outer surface of the storage tank body is covered with an insulation layer; the storage tank body is provided with a discharge port, and the discharge port is connected to the bagging machine through a discharge valve and a discharge barrel in sequence.

[0014] Furthermore, an on-off valve is provided between the sterilization, cooling and caching multifunctional integrated warehouse and the storage warehouse.

[0015] Furthermore, the sterilization, cooling and caching multifunctional integrated warehouse includes a sterilization tank body, a cooling interlayer spirally wound on the outer surface of the sterilization tank body, a second insulation layer wrapped around the outside of the cooling interlayer, and a stirring device arranged in the sterilization tank body.

[0016] Furthermore, the sterilization, cooling and caching multifunctional integrated warehouse also includes a vacuum pump and an air refrigerator respectively connected to the interior of the sterilization tank.

[0017] Furthermore, the cooling interlayer is connected to an underground cooling water pool through a water pump; there are at least two underground cooling water pools, each of which is connected to a cooling interlayer on each sterilization tank body. When in use, the water is cooled by a chiller and then enters the tank body interlayer for cooling.

[0018] Furthermore, the stirring device includes a first agitator rotatably connected to the sterilization tank body and a reducer transmission-connected to the first agitator; a passive sprocket is provided at one end of the first agitator; a driving sprocket is provided at the output end of the reducer; the driving sprocket and the passive sprocket are connected by a chain; and a motor is provided on the reducer.

[0019] The positive effects of this application are:

[0020] By setting the sterilization time of the sterilization and cooling cache multifunctional integrated warehouse to t1, the cooling time of the sterilization and cooling cache multifunctional integrated warehouse to t2, and the number n of the sterilization and cooling cache multifunctional integrated warehouses to be an integer of t1 / t2, for example, t1 / t2=2.5, then n is 3; the waiting phenomenon caused by long sterilization time and short cooling time can be avoided, thereby improving production efficiency;

[0021] The sterilization, cooling and caching multifunctional integrated warehouse can sterilize the tank during sterilization, avoiding the phenomenon of single disinfection of the original cooling warehouse and causing shutdown.

[0022] Originally, the reducer and the first auger were directly connected, which required the two to be concentric. During use, it was found that the coupling between the two was often damaged. After analysis, the main reason was that the output end of the reducer was not concentric with the first auger. If concentricity is to be guaranteed, the accuracy needs to be improved, which is time-consuming and labor-intensive. By setting up a stirring device including a reducer, an active sprocket, and a passive sprocket, instead of a direct connection, there is no need for coaxiality between the reducer and the first auger, which reduces the number of failures and improves efficiency.

[0030] Example 1

[0031] like Figures 1 to 3 As shown,

[0032] A new type of efficient multi-unit warehouse for sterilizing bulk edible fungi comprises a plurality of sterilization, cooling and caching multifunctional integrated warehouses 1 arranged in parallel and a storage warehouse 4 connected to the sterilization, cooling and caching multifunctional integrated warehouses 1; the number of the storage warehouses 4 is two, and each of the storage warehouses 4 is connected to each of the sterilization, cooling and caching multifunctional integrated warehouses 1 respectively.

[0033] The sterilization time of the sterilization and cooling cache multifunctional integrated warehouse 1 is t1, and the cooling time of the sterilization and cooling cache multifunctional integrated warehouse 1 is t2. The number of the sterilization and cooling cache multifunctional integrated warehouse 1 is n=t1 / t2, where n is an integer, for example, t1 / t2=2.5, then n is 3.

[0034] like Figure 1 As shown, there are three sterilization, cooling and caching multifunctional integrated warehouses 1, referred to as warehouse No. 1, warehouse No. 2 and warehouse No. 3;

[0035] like Figure 3 As shown, the storage bin 4 includes a storage tank body and an auger installed in the storage tank body, and the outer surface of the storage tank body is covered with an insulation layer; the storage tank body is provided with a discharge port, and the discharge port is connected to the bagging machine 52 through a discharge valve 51 and a discharge barrel 53 in sequence. The auger is an existing structure and will not be described again;

[0036] An on-off valve is provided between the sterilization, cooling and caching multifunctional integrated warehouse 1 and the storage warehouse 4 .

[0037] The sterilization, cooling and caching multifunctional integrated warehouse 1 comprises a sterilization tank body, a cooling interlayer 112 spirally wound on the outer surface of the sterilization tank body, a second thermal insulation layer 111 coated on the outside of the cooling interlayer, and a stirring device 11 arranged in the sterilization tank body.

[0038] The sterilization, cooling and caching multifunctional integrated warehouse 1 is provided with an exhaust valve for exhausting the steam after sterilization;

[0039] The sterilization, cooling and caching multifunctional integrated warehouse 1 is provided with a filling port 117 for adding raw materials that need to be sterilized;

[0040] The sterilization, cooling and caching multifunctional integrated warehouse 1 also includes a vacuum pump 13 and an air refrigerator 14 respectively connected to the interior of the sterilization tank. The air refrigerator 14 is provided with compressed air by an air compressor;

[0041] The vacuum pump 13 is used to evacuate the sterilization tank; the air refrigerator 14 is used to pass air that needs to be cooled into the sterilization tank;

[0042] The cooling interlayer is connected to the underground cooling water pool 6 through a water pump 17; there are at least two underground cooling water pools 6, each of which is connected to the cooling interlayer 112 on each sterilization tank body. At least two underground cooling water pools 6 are provided, so that when one pool is in use, the other pool can be used for water drying and cooling;

[0043] The stirring device 11 includes a first agitator 113 rotatably connected to the sterilization tank body and a driving device for driving the first agitator 113 to rotate.

[0044] The present application also includes a controller, which is provided with a timer. The controller is used to control the water pump 17, the driving device of the stirring device, the vacuum pump, the air refrigerator and the opening and closing of each valve; the controller also receives the signal of the temperature sensor on the tank body and the water temperature of the water pool. According to the signal of the temperature sensor, it is judged whether the cooling is in place;

[0045] The working process of this application,

[0046] For the convenience of description, Figure 1 As shown, there are three sterilization, cooling and caching multifunctional integrated warehouses, referred to as warehouse No. 1, warehouse No. 2 and warehouse No. 3; there are two storage warehouses 4, divided into storage warehouse No. 1 and storage warehouse No. 2;

[0047] Due to the high cooling efficiency, the sterilization time of the sterilization chamber is 3 times that of the cooling time, and the efficiency is seriously mismatched. Therefore, the three-bin combination of the traditional (existing) bulk sterilization coupling equipment cannot meet the needs of efficient production of edible mushroom bags (sticks). Therefore, the present application has deliberately made substantial principle and structural improvements. The sterilization, cooling and caching multifunctional integrated bin designed in accordance with the latest principle is composed of 3-4 bins. When the base materials such as sawdust, ambush, water, etc. are fully mixed by the mixer and input into the multifunctional sterilization and cooling bin No. 1 by the elevator, the feed port 117 is closed; the No. 1 bin starts to stir and start to fill with steam. When the temperature in the bin rises to 123-125°C, the pressure is maintained for 110-120 minutes. After the timing ends, the system automatically opens the exhaust valve to exhaust and reduce pressure. When the pressure is close to zero, the cooling water switch of the interlayer of the No. 1 bin is turned on, and the water pump 17 is turned on. The cooling water enters the cooling interlayer 112 of the tank body and starts to cool down. The vacuum pump 13 of the vacuum system also starts to start to extract the hot air in the No. 1 warehouse and discharge it to the outside of the warehouse. When the warehouse is close to negative pressure, the system starts the air compressor and the air refrigerator 14 again, and the sterile air filtered by the air filtration system enters the No. 1 warehouse to cool the air in the warehouse. The three cooling systems circulate to cool the No. 1 warehouse at the same time. When the temperature of the base material in the warehouse drops to 28°C, the stirring is stopped, and the discharge valve on the discharge pipe 15 of the No. 1 warehouse can be opened to start discharging the material to the storage warehouse No. 1. When the storage warehouse No. 1 receives the discharge, the discharge valve of the No. 1 warehouse and the storage warehouse No. 1 is automatically closed, and the storage warehouse No. 1 starts to open the lower discharge valve 51 to start discharging the material to the storage working warehouse of the bagging machine 52 below. The bagging machine 52 starts the packaging (rod) program. The above is the whole process of the operation of the first (level) sterilization and cooling warehouse 1.

[0048] The cooling process takes about 30-40 minutes; in this way, warehouse No. 1 is cooled, and warehouse No. 2 and warehouse No. 3 are filled, sterilized, and cooled in turn. The three warehouses circulate a set of steam equipment, water pump 17, vacuum pump 13, air refrigerator 14, and air compressor (in order to show the working principle in the figure, each warehouse is equipped with the above equipment), saving investment.

[0049] After the input of edible fungus base material in warehouse No. 1 is completed, the base material conveying system immediately inputs the base material to sterilization warehouse No. 2, and then starts to repeat the whole sterilization process with warehouse No. 1. After the sterilization process in sterilization warehouse No. 2 is completed, the whole sterilization process in sterilization warehouse No. 3 is started immediately. If there is a sterilization warehouse No. 4, the working procedure is also started in a cycle according to this procedure. When the base material in storage warehouse No. 1 is consumed by the bagging machine, the base material in sterilization warehouses No. 2-3-4 is continuously circulated and conveyed, and so on and so forth;

[0050] The present application has better solved the perfect matching of the time allocation and utilization between the sterilization efficiency of the sterilization chamber and the cooling efficiency of the cooling chamber. Therefore, the present application has obvious efficiency and technical advantages over the existing bulk material sterilization devices.

[0051] The present application designs a double cooling bin in order to solve the design drawbacks of the existing bulk material sterilization bins, which use single-channel (level) cooling bins and storage bins for sterilization for multiple days at a time. The 3-4-channel (level) multifunctional sterilization bin designed in the present application is not affected by pollution factors because it needs to be sterilized continuously every day. At the same time, the functions of the traditional (existing) cooling bins are integrated into the working range of the multifunctional sterilization bin of the present application. Therefore, the present application does not have the problem that the cooling bin needs to be sterilized every 6-7 days, and of course there is no contamination in the bin during use. The traditional (existing) bulk material sterilization single-channel (level) cooling bins and single-channel (level) storage bins have only one channel (level), so they cannot be like the double storage bin invented in the present application. , you can switch between storage bins 1 and 2 anytime and anywhere, that is, when storage bin 1 is working normally, you can switch to storage bin 2 for packaging (rod) work at any time (storage bin 2 must be sterilized in advance when switching to storage bin 1). Similarly, after working in storage bin 2 for a period of time, if the process requires switching back to storage bin 1, sterilize storage bin 1 in advance, and then switch back to storage bin 1. While sterilizing, the unloading barrel of the storage bin is also sterilized simultaneously. This forms a fairly perfect bulk material sterilization circulation system, which maximizes the consumption and utilization of the time and space generated by each sterilization process, and of course produces more significant production efficiency, and the use value has been steadily improved by a large step.

[0052] Example 2

[0053] The difference between this embodiment and embodiment 1 is that:

[0054] like Figure 2 As shown,

[0055] The original stirring was driven by a high-power motor and a coupling directly connected to one end of the auger. As the required output increased, the volume of the sterilization tank increased, and the required motor power was very large, which was not economical. The direct connection method required very high concentricity and was prone to failure due to manufacturing precision issues, so further improvement was needed.

[0056] The driving device includes a reducer 114 which is transmission-connected to the first agitator 113; a passive sprocket 115 is provided at one end of the first agitator 113; a driving sprocket 116 is provided at the output end of the reducer 114; the driving sprocket 116 and the passive sprocket 115 are connected by a chain; and a motor is provided on the reducer 114.

[0057] There are two reducers 114, which are respectively arranged at the two ends of the first auger 113. The reducer 114 transmits power to the first auger 113 through a sprocket chain.

[0058] By providing the reducer 114, the power of the motor can be reduced, thereby reducing energy consumption.

[0059] Example 3

[0060] The structure of this embodiment is basically the same as that of embodiment 1.

[0061] The difference is that

[0062] After the circulating water in the traditional (existing) sterilization chamber is discharged from the tank, it is cooled in the cooling tower and then recycled. The cooling tower water is greatly affected by the weather and the water temperature is unstable.

[0063] A more reasonable design scheme is now proposed. The cooling water of the sterilization and cooling cache multifunctional integrated warehouse 1 flows directly into an underground water storage tank that is large enough to accommodate the water cooled to 28°C by the sterilization and cooling cache multifunctional integrated warehouse 1. There are two to four water storage tanks in total, namely, No. 1 water storage tank, No. 2 water storage tank, No. 3 water storage tank, and No. 4 water storage tank. The water tank is equipped with a temperature measuring device. If the water temperature of the water tank exceeds 32 degrees, the water supply will be switched to the second water tank.

[0064] The principle of use is:

[0065] When the sterilization is started for the first time, the sterilization, cooling and caching multifunctional integrated warehouse 1 uses all well water for cooling. All the cooling water produced by the sterilization, cooling and caching multifunctional integrated warehouse 1 on the first day flows into the No. 1 water storage tank for continued cooling. When the temperature exceeds 32 degrees, the water in the second water tank is used for cooling. When sterilizing and cooling on the second day, the water in the water storage tank on the first day is used. The water in the water storage tank at this time is cooled underground overnight and then sucked into the chiller through a pipe pump. The water cooled by the chiller is at a constant temperature, which is low and constant. After entering the interlayer of the sterilization, cooling and caching multifunctional integrated warehouse 1, it enters the No. 2 underground water storage tank, and so on, and is circulated. The design scheme has obvious advantages over the existing cooling tower cooling system, which has the defects of uncontrollable water temperature and is affected by weather and region.

[0066] The above-mentioned embodiments are described in a relatively detailed and specific manner, expressing the preferred embodiments of the present application. They are only used to illustrate the technical ideas and features of the present application. Their purpose is to enable technicians in this field to understand the contents of the present application and implement them accordingly. However, they are not limited to the present application. The patent scope of the present application cannot be limited only by the embodiments. That is, any equivalent changes or modifications made to the spirit disclosed in the present application, for researchers or technicians in this field, without departing from the structure of the present application, local improvements within the system and changes and transformations between subsystems, etc., are still within the patent scope of the present application.
