Description

Technical Field

[0001] The invention belongs to the technical field of fruit juice preparation and sterilization, and particularly relates to a preparation and sterilization system in the production of bayberry juice. Background Art

[0002] Juice is the juice extracted from fresh fruits after selection, washing and squeezing. It is rich in vitamins, minerals, carbohydrates and dietary fiber. It is the most nutritious part of fruits and is easily absorbed by the human body. It is close to fresh fruits in flavor and nutrition and is known as "liquid fruit". Juice is the main processing and consumption form of fruits in developed countries. The volume and weight of fruits processed into concentrated juice products are greatly reduced, which can effectively reduce storage and transportation costs and become the main fruit processing products in international trade. With the improvement of living standards year by year, people's dietary structure is gradually changing. Not only has the demand for juice increased significantly, but also higher requirements have been put forward for the quality of juice. The demand for natural, high-quality, healthy and nutritious pure juice and concentrated juice has increased by more than 20%, gradually becoming the development trend and direction of China's juice consumption.

[0003] Bayberry is a common fruit and an excellent tree species for landscaping and production. It is suitable to plant it alone or in clusters on lawns, courtyards, or in rows on the roadside. It is also ideal to use dense planting to separate spaces or provide shelter. Economic Uses: The fruit has a moderate sweet and sour taste. It can be eaten directly, processed into dried bayberries, sauces, candied fruits, etc., and can also be used to make wine. It has the functions of quenching thirst, promoting salivation, and aiding digestion. Bayberry juice is also loved by consumers because of its good taste. Bayberry juice production requires multiple processing steps, and sterilization is one of the important steps. The existing mixing and sterilization device has a long sterilization time, which is not conducive to the improvement of production capacity. In addition, the existing mixing and sterilization device can only sterilize bayberry juice, and its function is relatively single. It cannot filter and remove impurities in the bayberry juice, which greatly reduces the taste and quality of the bayberry juice. Summary of the invention

[0004] The purpose of the present invention is to provide a mixing and sterilizing system in the production of bayberry juice to solve the problems existing in the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides a mixing and sterilizing system in the production of bayberry juice, comprising a material barrel, a homogenizer, a mixing tank, a sterilizer and a heat pump circulation device;

[0033] Embodiment 1

[0034] like Figure 1-Figure 3 As shown, this embodiment provides a preparation and sterilization system for bayberry juice production, including a material barrel 1, a homogenizer 2, a preparation tank 3, a sterilizer and a heat pump circulation device;

[0035] The material barrel 1, the homogenizer 2, the mixing tank 3 and the sterilizer are connected in sequence, and a preheating box 6 is installed on the feed pipe of the material barrel 1; a heating pipe is arranged in the preheating box 6, and the heating pipe is spirally wound on the outer wall of the feed pipe of the material barrel 1, and the heating pipe is connected to the heat pump circulation device.

[0036] The material barrel 1, the homogenizer 2, and the mixing tank 3 may be provided with a screw pump at the discharge port.

[0037] The material barrel 1, homogenizer 2, and mixing tank 3 can all be connected to the CIP system, and each device is connected to the CIP (clean in place) system, which is convenient for automatic cleaning and disinfection of the equipment during and after the production process, thereby improving production efficiency and hygiene standards.

[0038] This embodiment involves the field of juice blending and sterilization technology, and provides a set of efficient and integrated bayberry juice production, blending and sterilization system. The system exquisitely integrates material barrels, efficient homogenizers, precision blending tanks, advanced sterilizers, and environmentally friendly and energy-saving heat pump circulation devices to form a smooth and optimized production line. This system takes the material barrel as the starting point, and adds a preheating box link before the material enters the material barrel. In the preheating box, the spirally wound heating pipe is closely connected to the heat pump circulation device to ensure that the material is evenly preheated during the transportation process, effectively improving the efficiency and effect of subsequent processing. The preheated material first undergoes the first fine filtration to remove large particles of impurities, and then enters the homogenizer.

The emulsified material is strictly filtered again to ensure purity. Then, the material enters the precision blending tank. Through the blender, various ingredients are evenly blended. Then, the finished juice enters the advanced sterilizer, using efficient sterilization technology to fully kill harmful microorganisms and ensure product safety. After sterilization, the juice is sent to the cost tank for storage. The bayberry juice production and preparation sterilization system of the present invention not only significantly improves the filtering, emulsification and sterilization effects, but also achieves energy saving and environmental protection in the production process while ensuring product quality. This innovative achievement will undoubtedly set a new benchmark for the juice processing industry and lead the industry to develop in a more efficient, greener and higher quality direction.

[0039] CIP system, full name is Clean In Place, which is a cleaning in place (online cleaning, cleaning in place) system. This system is widely used in the production process of food, beverage, pharmaceutical and other industries. It is an efficient and automated cleaning equipment. CIP system is widely used in various beverages (such as milk beverages, fruit and vegetable juice beverages, fruit beverages, tea beverages, etc.), liquid milk, yogurt, alcohol and other food companies with a high degree of mechanization. In fact, it is the cleaning inside the production equipment, such as the inside of the pipe, the inside of the cylinder, etc.

[0040] The working principle of the CIP system is to send cleaning liquid into the equipment through a circulating pump, and use physical or chemical forces to remove dirt and residues inside the equipment, thereby achieving the purpose of cleaning the equipment.

[0041] This embodiment adopts a CIP system to achieve timely online cleaning. The entire system runs smoothly and can work continuously for a long time, which meets actual use requirements.

[0042] The sterilizer adopts a tubular sterilizer 4, which is a sterilizing and cooling device. The operation mode is usually touch screen operation to achieve full automatic control, and is equipped with a self-cleaning and reverse cleaning system to ensure the sanitation and efficient operation of the equipment. The tubular sterilizer kills microorganisms in the material through high temperature treatment, thereby achieving the purpose of sterilization.

[0043] Working principle of tubular sterilizer: the material first enters the preheating section of the tubular sterilizer for preliminary heating. Then, the material enters the high-temperature sterilization section and is subjected to high-temperature treatment at the set temperature and time to ensure that all harmful microorganisms are killed. After the sterilization is completed, the material enters the cooling section for rapid cooling to retain the nutritional content and taste of the product.

[0044] Bayberry is a common fruit and an excellent tree species for landscaping and production. It is suitable to plant it alone or in clusters on lawns, courtyards, or in rows on the roadside. It is also ideal to use dense planting to separate spaces or provide shelter. Economic Uses: The fruit has a moderate sweet and sour taste. It can be eaten directly, processed into dried bayberries, sauces, candied fruits, etc., and can also be used to make wine. It has the functions of quenching thirst, promoting salivation, and aiding digestion. Bayberry juice is also loved by consumers because of its good taste. Bayberry juice production requires multiple processing steps, and sterilization is one of the important steps. The existing mixing and sterilization device has a long sterilization time, which is not conducive to the improvement of production capacity. In addition, the existing mixing and sterilization device can only sterilize bayberry juice, and its function is relatively single. It cannot filter and remove impurities in the bayberry juice, which greatly reduces the taste and quality of the bayberry juice.

[0045] The present embodiment provides a preparation and sterilization system for bayberry juice production, in which double filters 5 are respectively arranged between the material barrel 1 and the homogenizer 2, and between the homogenizer 2 and the preparation tank 3. The double filtration effectively removes impurities and particles in the material, thereby ensuring the purity and taste of the product. The present embodiment provides a preheating device at the feed port of the material barrel 1. The preheating device reduces the sterilization time of the subsequent tubular sterilizer 4 by preheating in advance, thereby facilitating the improvement of production capacity.

[0046] In this embodiment, the juice is preheated before being added to the material barrel 1, and the first filtration is performed after the preheating is completed, and then it enters the homogenizer 2 for emulsification. The emulsified material is filtered and further blended, and the material is evenly stirred through the blending tank 3 to form a finished juice product, which is sterilized and finally stored in the cost tank. This embodiment can improve the filtering effect, emulsification effect and sterilization effect, and improve the product quality. The equipment of this embodiment is highly integrated: the entire system from the material barrel 1 to the sterilizer is tightly connected between the various devices, and the process is smooth, which reduces the risk of contamination during material transfer and improves the level of production automation.

[0047] It is feasible that a first duplex filter is provided between the material barrel 1 and the homogenizer 2 , and a second duplex filter is provided between the homogenizer 2 and the blending tank 3 .

[0048] The duplex filter is mainly composed of two single-tube filters assembled on a base. Each single-tube filter contains filter cylinder, barrel cover, valve, filter bag net, pressure gauge and other components. The equipment is usually made of stainless steel, such as SUS304 stainless steel, to ensure its corrosion resistance and durability. The duplex filter has high filtration accuracy and a wide filtration range. It can filter fine particles or suspended matter from 0.5 to 200 microns. It has high filtration efficiency, large processing flow per unit filtration area, and low filtration resistance.

[0049] The preheating box 6 also includes a temperature indicator, which is installed on the outer wall of the feed pipe of the material barrel 1. The temperature indicator provided in the preheating box 6 can monitor the material temperature in real time, ensuring that the material reaches the ideal preheating temperature before entering the subsequent processing link, thereby improving product quality.

[0050] It can be implemented that the heat pump circulation device includes an air cooler 8, a flash tank 11 and a water tank 10; a water level sensor is provided in the water tank 10, the water inlet of the flash tank 11 is connected to the heat absorption side outlet of the air cooler 8, the water outlet of the flash tank 11 and the water outlet of the water tank 10 are both connected to the heat absorption side inlet of the air cooler 8, the water outlet of the flash tank 11 is also connected to the water inlet end of the heating pipe, and the water outlet end of the heating pipe is connected to the heat absorption side inlet of the air cooler 8.

[0051] The heat pump circulation device further includes a booster pump 9, which is arranged at the heat absorption side inlet of the air cooler 8. The heat pump circulation device further includes a steam compressor 12, the air inlet of the steam compressor 12 is connected to the air outlet of the flash tank 11, the water inlet of the steam compressor 12 is connected to the water tank 10, and the air outlet of the steam compressor 12 is connected to the sterilizer. Through the heat pump circulation device, the flash tank 11 and the steam compressor 12 are used to realize the recovery and reuse of heat energy, which significantly improves the energy utilization efficiency and reduces the production cost.

[0052] It is feasible that the medium inlet of the air cooler 8 is connected to the compressor 7 .

[0053] The implementation process of this embodiment includes:

[0054] Material pretreatment: Put the raw material bayberry into the material barrel 1, and preheat the material through the heating pipe in the preheating box 6, and the heating pipe is provided with heat source by the heat pump circulation device.

[0055] Homogenization: The preheated material passes through the first double filter and enters the homogenizer 2 for refinement to make the material more uniform and fine.

[0056] Preparation: The homogenized material enters the preparation tank 3, and other raw materials are added according to the formula for preparation. During this period, impurities are removed through the second double filter.

[0057] Sterilization: The prepared bayberry juice enters the tubular sterilizer 4 through a pipeline for high-temperature sterilization to ensure the safety and shelf life of the product.

[0058] Finished product storage: The sterilized bayberry juice enters the finished product storage tank or undergoes subsequent processing such as filling.

[0059] The assembly process of this embodiment includes:

[0060] Installation of basic equipment: First install the basic frame and supporting structure of the material barrel 1, homogenizer 2, mixing tank 3, sterilizer and heat pump circulation device.

[0061] Pipeline connection: According to the process flow chart, connect the pipelines between the material barrel 1, preheating box 6, homogenizer 2, duplex filter 5, mixing tank 3, sterilizer and heat pump circulation device in sequence, and ensure that the connection is tight and there is no leakage.

[0062] Equipment installation: install the preheating box 6, duplex filter 5, air cooler 8, flash tank 11, water tank 10, booster pump 9, steam compressor 12 and other equipment to the designated location according to the design drawings and fix them.

[0063] Electrical control: Install and debug the electrical control systems of each device, including temperature sensors, pressure sensors, liquid level sensors, etc., to ensure that the equipment can operate automatically according to preset parameters.

[0064] System debugging: Debug the entire system, check whether the coordination between various devices is smooth, adjust parameters to the optimal state, and ensure that the system can run stably and meet the design requirements.

[0065] Cleaning and disinfection: After the system is debugged, the entire system is cleaned and disinfected to ensure that the hygiene standards in the production process meet the requirements.

[0066] The bayberry juice production, preparation and sterilization system of this embodiment significantly improves the precision of the production process and the product quality. A double filter 5 is cleverly arranged between the material barrel 1 and the homogenizer 2, and between the homogenizer 2 and the preparation tank 3. This double filtering mechanism is like two precise barriers, which effectively removes fine impurities and particles in the material, ensuring the purity of the bayberry juice, thereby retaining its natural flavor and delicate taste.

[0067] The system innovatively integrates a preheating device at the feed port of the material barrel 1. By preheating the raw materials gently and evenly, it not only shortens the processing time of the subsequent tubular sterilizer 4, but also promotes a leap in production efficiency and achieves a significant increase in production capacity.

[0068] In the production process, after the first filtration, the material enters the homogenizer 2 for fine emulsification. The emulsified material has a finer and smoother texture, and then passes through the second filtration to ensure the filtration effect. Then, the material enters the blending tank 3, and after sufficient stirring and mixing, the preliminary bayberry juice product is obtained.

[0069] The subsequent sterilization process, thanks to the preliminary preheating, is not only more efficient but also more effective, ensuring that the bayberry juice kills harmful microorganisms while retaining its rich nutrients and delicious flavor.

[0070] In summary, this embodiment improves the production efficiency and product quality of bayberry juice in all aspects by optimizing key links such as filtration, emulsification, blending and sterilization, and brings consumers a purer, more delicate and delicious taste experience.
