Description

Technical Field

[0001] This utility model relates to the field of fermentation equipment technology, specifically a device suitable for semi-solid fermentation of bee pollen. Background Technology

[0002] Bee pollen is rich in nutrients and is hailed as an "all-around nutrient," making it an important source of dietary nutrition. However, bee pollen itself has a certain bitterness and earthy taste, a sensory defect that seriously affects people's appetite. Fermentation, as an important processing method to improve the sensory quality of food and extend its shelf life, is widely used in the food processing industry. Among them, probiotic fermentation of bee pollen can not only effectively reduce the bitterness of bee pollen but also further enhance its nutritional value, making it an important processing method in the bee pollen processing industry.

[0003] Currently, most commercially available fermentation tanks are designed for liquid fermentation, such as fruit wine and fruit vinegar. However, the water added during bee pollen fermentation is only 30-70% of the bee pollen's mass, making it a semi-solid fermentation system. Existing liquid fermentation tanks present two major problems when applied to semi-solid bee pollen fermentation: first, insufficient mixing makes it difficult to achieve uniform mixing of semi-solid materials, resulting in uneven contact between probiotics and bee pollen during fermentation, affecting the fermentation effect; second, unloading is difficult, as semi-solid materials easily adhere to the tank's inner wall and bottom, and existing discharge structures cannot achieve complete material release, leading to raw material waste and increased cleaning difficulty. Furthermore, some existing fermentation tanks lack specific sterilization, temperature control, and fermentation status monitoring structures, failing to meet the requirements of a sterile environment, precise temperature control, and real-time observation during bee pollen fermentation. Therefore, there is an urgent need for a fermentation tank specifically adapted to the needs of semi-solid bee pollen fermentation, integrating thorough mixing, complete unloading, sterile processing, precise temperature control, and status monitoring.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Please see Figures 1-3 This is the first embodiment of the present utility model.

[0031] This embodiment provides an apparatus suitable for semi-solid fermentation of bee pollen, comprising:

[0032] Tank body 1 and tank lid 2;

[0033] Feed inlet 3 is installed on one side of the surface of the can cover 2;

[0034] Discharge port 14 is installed at the bottom of tank body 1;

[0035] Hot water inlet 15 is installed on one side of the bottom of tank body 1;

[0036] Bracket 6 is installed on one side of the surface of the can lid 2;

[0037] Motor 7 is mounted on the top of bracket 6, and one end of the output shaft of motor 7 is connected to a stirring component 10 via a coupling.

[0038] For example, the tank body 1 is a stainless steel sandwich structure, made of food-grade stainless steel. A base 16 is fixedly installed at the bottom of the tank body 1. The base 16 is made of cast iron and has an anti-slip pad on its surface to improve the stability of the tank body.

[0039] For example, a pressure inlet 4 is installed on the other side of the surface of the can lid 2. The pressure inlet 4 is equipped with a pressure gauge and a pressure relief valve, which can monitor the pressure inside the can in real time and automatically release pressure when the pressure exceeds the standard, so as to ensure the safety of the fermentation process.

[0040] For example, a breather 5 is installed at the center of the surface of the can lid 2. The breather 5 has a filter membrane inside, which can realize the exchange of gases between the inside and outside of the can, while preventing external bacteria from entering the can and maintaining a sterile fermentation environment.

[0041] Furthermore, the can lid 2 is a circular stainless steel plate, and the can lid 2 is fixedly connected to the can body 1 by 8 evenly distributed bolts. The sealing gasket at the connection is made of food-grade silicone. The feed port 3 is welded to the left side of the can lid 2, and the sealing cover is connected to the feed port 3 by threads.

[0042] For example, the support 6 has a gate-shaped structure, the motor 7 is a variable frequency motor, and a sealing element 11 is fitted at the penetration point between the stirring element 1 and the tank cover 2 to ensure the tank's airtightness.

[0043] Furthermore, the respirator 5 is a sterile respirator with a 0.22μm filter membrane inside. The respirator 5 is connected to the canister cap 2 by a thread, which facilitates the disassembly and replacement of the filter membrane.

[0044] For example, a steam inlet 12 is provided on the lower side wall of the tank body 1. The steam inlet 12 is connected to an external steam generator through a pipe. A valve is provided on the pipe to control the on / off state, which is used to introduce steam into the jacket and interior of the tank body 1 for sterilization. A hot water inlet 15 is provided on one side of the bottom of the tank body 1, and a hot water outlet 13 is provided on the upper side wall of the tank body 1. Both the hot water inlet 15 and the hot water outlet 13 are connected to an external hot and cold water exchanger to form a circulating water circuit, which is used to control the temperature of the material inside the tank.

[0045] Furthermore, multiple sets of spiral impellers are welded onto the stirring shaft of the stirring component 10.

[0046] For example, a removable sealing plug is provided at the discharge port 14, and a push plate adapted to the discharge port 14 is provided on the inner side of the bottom of the tank body 1. The push plate is driven by an electric push rod and can push the semi-solid material adhering to the inner wall and bottom of the tank to the discharge port 14 to ensure that the material is completely released.

[0047] Furthermore, the sealing plug is made of food-grade rubber, and the push plate has a circular structure with a diameter that matches the inner diameter of the tank body.

[0048] In use, first, fix the tank 1 on the base 16 to ensure it is stable; open the sealing cover of the feed inlet 3, add the bee pollen raw material and an appropriate amount of water to the tank 1 at a ratio of 30% of the bee pollen mass, and close the sealing cover of the feed inlet 3; connect the external steam generator through the steam inlet 12, open the valve to introduce steam into the tank 1, and perform high-temperature sterilization for 30 minutes. During sterilization, monitor the pressure inside the tank through the pressure gauge at the pressure port 4. If the pressure exceeds 0.3 MPa, the pressure relief valve will automatically open to release pressure; after sterilization, close the steam valve and wait for the temperature inside the tank to drop to the suitable fermentation temperature; connect the hot water inlet 15 and the hot water outlet 13 to an external hot and cold water exchanger. The equipment is set up by starting the circulating water pump and adjusting the hot and cold water exchanger to stabilize the material temperature inside the tank at 25℃. The motor 7 is started, and the speed is adjusted to 50r / min via the frequency converter to drive the agitator 10 to mix the material. After mixing for 10 minutes, the speed is adjusted to 30r / min to maintain the mixing state and ensure uniform fermentation of the material. During the fermentation process, the gas exchange between the inside and outside of the tank is achieved through the breather 5 to prevent the entry of miscellaneous bacteria. The pressure is monitored periodically through the pressure inlet 4. After the fermentation is completed, the motor 7 and the hot and cold water exchanger are turned off, the sealing plug of the discharge port 14 is removed, the electric push rod is started, and the push plate is pushed to completely push the semi-solid fermented material in the tank out of the discharge port 14 to complete the unloading.

[0049] In summary, by setting up an extended spiral stirring component and pairing it with a variable frequency motor drive, it is possible to achieve full and uniform stirring based on the characteristics of semi-solid fermented bee pollen materials, ensuring that probiotics and bee pollen materials are in full contact, thereby improving fermentation efficiency and product quality. At the same time, the steam inlet 12, in conjunction with the external steam generator, can achieve aseptic treatment inside the tank, and the breather 5 ensures gas exchange during fermentation and prevents contamination by miscellaneous bacteria, providing a clean environment for fermentation.

[0050] The tank body features a double-layer structure with a hot and cold water exchanger, enabling precise temperature control within the tank to meet the temperature requirements of different probiotic fermentations. The large-diameter discharge port, combined with an electric pusher plate structure, solves the problems of difficult unloading and severe residue of semi-solid materials, reducing raw material waste and facilitating cleaning. The pressure inlet allows for real-time monitoring of the tank pressure, ensuring a safe and stable fermentation process.

[0051] Please see Figures 1-3 This is the second embodiment of the present utility model.

[0052] For example, the volume of the tank 1 is 50L, it is made of 316 food-grade stainless steel, the wall thickness of the tank 1 is 5mm, the diameter of the base 16 is 15cm larger than the bottom diameter of the tank 1, and the anti-slip pad at the bottom of the base 16 is 10mm thick to improve the anti-slip effect.

[0053] Furthermore, the number of bolts connecting the can lid 2 to the can body 1 is 12, the diameter of the feed inlet 3 is 12cm, and a sealing ring is provided on the inner side of the sealing cover to enhance the sealing performance.

[0054] For example, the pressure gauge in pressure port 4 is a digital display pressure gauge with an accuracy of ±0.01MPa, and the pressure relief valve is an automatic pressure relief valve, whose opening pressure can be adjusted via the control panel.

[0055] Furthermore, the respirator 5 has a dual-membrane structure, and the membranes can be repeatedly washed and reused, reducing operating costs. The respirator 5 also has a sealing gasket at the interface to ensure a tight seal.

[0056] For example, the bracket 6 has a height of 40cm, the motor 7 has a power of 1.5kW, the equipped frequency converter can achieve stepless speed adjustment within the range of 30-120r / min, and the seal 11 is a combined mechanical seal, which has more reliable sealing performance.

[0057] Furthermore, the stirring shaft of the stirring component 10 has a diameter of 25mm, and four sets of spiral stirring blades are welded on the stirring shaft. The surface of the stirring blades is coated with a wear-resistant coating to extend their service life.

[0058] During use, add bee pollen raw materials and water to a 50L tank 1 at a ratio of 70% of the bee pollen mass, and close the inlet 3 and the sealing plug. Set the steam sterilization parameters through the control panel, start the external steam generator, and the solenoid valve will automatically open to introduce steam into the tank 1. Set the sterilization time to 20 minutes. During sterilization, the digital pressure gauge will display the pressure inside the tank in real time, and the pressure relief valve will automatically maintain a stable pressure. After sterilization, the solenoid valve will automatically close, the hot and cold water exchanger will adjust the temperature inside the tank according to the preset temperature curve, and the circulating water pump will drive the water flow in the jacket to ensure uniform temperature inside the tank. Motor 7, with its speed adjusted to 100 r / min via frequency converter, drives the agitator 10 to thoroughly stir the relatively thin semi-solid material. After stirring for 15 minutes, the speed is adjusted to 50-80 r / min according to the fermentation stage. During fermentation, aseptic gas exchange is achieved through the breather 5, and the digital pressure gauge at the pressure inlet 4 is checked regularly to ensure a stable fermentation environment. After fermentation, the system automatically shuts off motor 7 and the hot and cold water exchanger, loosens the sealing plug connected to the flange, adjusts the extension and retraction speed and stroke of the electric push rod, and pushes the material in the tank to the discharge port 14 completely, achieving rapid and residue-free unloading.

[0059] In summary, the fermenter in this embodiment has a larger volume, and the stirring effect, sealing performance, temperature control accuracy and ease of operation are all improved. It can meet the semi-solid fermentation needs of bee pollen with different water additions and different fermentation scales, and has a wider range of applications, making it more suitable for industrial production applications.

[0060] All technical features in this embodiment can be freely combined according to actual needs.

[0061] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
