Description

Technical Field

[0001] This invention relates to the field of feed cooling technology, and in particular to a feed cooling device and cooling method. Background Technology

[0002] Feed is a general term for the food of animals raised by humans. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. Nowadays, in the production process of feed on the market, depending on the output, automated production is required in the processing workshop. During the production process, especially in the summer months of July to September, the temperature in the feed processing workshop is high, which leads to the feed being hot and slow to cool down after production. This can cause problems such as mold and low moisture content in the feed, which greatly shortens the shelf life of the feed and reduces the input-output ratio of production. Summary of the Invention

[0003] In view of the above-mentioned problems in the prior art, the present invention aims to provide a feed cooling device and a cooling method, which solves the problems of high feed temperature, slow cooling, mold growth and shortened shelf life caused by the lack of cooling equipment in existing feed processing workshops.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows:

[0014] The cooling assembly is used to cool the air supplied by the blower and deliver the cooled air into the tank.

[0015] Furthermore, a filtration device is provided between the blower assembly and the cooling assembly. The filtration device includes a filter box, and a filter layer is provided inside the filter box. The filter layer includes a quartz sand layer, an activated carbon layer, and a filter element layer.

[0016] An installation notch is provided on the outer wall of the filter box, and a fixing buckle is provided at the corresponding position of the installation notch when viewed from the front. The filter layer passes through the installation notch and is installed inside the filter box, and the bottom of the filter layer is connected to the fixing buckle.

[0017] Furthermore, the cooling assembly includes a cooling cavity, the two ends of which are connected to a blower and a cooling pipe respectively via pipes;

[0018] The cooling chamber is equipped with a vortex tube, and the tube wall of the vortex tube is provided with a tangential inlet, which is connected to the high-pressure gas.

[0019] The two ends of the vortex tube are respectively equipped with a hot air duct and a cold air duct. The hot air duct discharges the hot gas inside the vortex tube to the outside, while the cold air duct has a curved spiral structure and is located on the outer wall of the cooling cavity.

[0020] Furthermore, a humidification module is provided between the cooling cavity and the tank. The humidification module includes a humidification cavity, and a sealing partition is provided inside the humidification cavity. The sealing partition is used to divide the humidification cavity into an upper cavity and a lower cavity.

[0021] The two sides of the upper cavity are connected to the cooling cavity and the cooling pipe respectively through pipes;

[0022] The lower cavity is filled with water, and an ultrasonic oscillating plate is placed in the water to agitate the water into a water mist.

[0023] A mist outlet pipe is provided on the sealing partition, which is used to transport water mist from the lower cavity to the upper cavity.

[0024] Furthermore, the material cooling equipment also includes a control module, which includes a controller;

[0025] A temperature sensor is installed inside the cooling chamber; a humidity sensor is installed inside the humidification chamber.

[0027] Furthermore, the air temperature inside the cooling chamber is 8-10℃, and the air humidity inside the humidification chamber is 40-60%.

[0028] The present invention also provides a cooling method for a feed cooling device, comprising:

[0029] Step 1: Ground preparation: Before installing the feed cooling equipment, prepare the ground in the feed workshop to ensure that the ground is level;

[0030] Step Two: Equipment Installation: Install the feed cooling equipment on a level surface. Multiple feed cooling tanks will be installed indoors, while the blowers and hot air ducts from the cooling module will be installed outside the feed processing workshop. After installation, set the cooling equipment parameters: cooling time for the feed cooling tanks should be 3-5 hours, and blower airflow should be 20,000 m³ / h. 3 / h, the cooling module's cooling temperature is 8-10℃, and the humidification module's air humidity is 40-60%;

[0031] Step 3, Fresh air filtration: The filtration equipment filters the air supplied by the blower;

[0032] Step 4: Cooling and Humidification: The cooling module cools the filtered air. Once the air in the cooling module reaches the specified temperature, it is sent to the humidification module to humidify the cooled air.

[0033] Step 5, Centrifugal air supply: After the air is cooled and humidified, it is pressurized and transported by a blower to deliver the treated air into the cooling pipes;

[0034] Step Six: Cooling: Start the stirring motor. The stirring motor stirs the feed in the tank through the stirring shaft and stirring blades. At the same time, the treated air is sprayed out through multiple gas nozzles to cool and humidify the feed in the tank until the cooling time of the feed cooling tank is reached, thus completing the cooling and humidification treatment of the feed.

[0035] The beneficial effects of this invention are as follows:

[0036] 1. The feed cooling equipment of the present invention is equipped with multiple feed cooling tanks and cooling modules. The feed cooling tanks are used to store the processed feed, and the cooling modules are used to deliver cooling air to the multiple feed cooling tanks to cool the feed inside the tanks, thereby avoiding the occurrence of mold growth caused by excessive internal temperature of the feed and extending the shelf life of the feed.

[0037] 2. The mixing device in the feed cooling tank and the multiple gas nozzles on the cooling pipes are designed to rapidly cool the feed during the cooling process. The mixing device stirs the feed inside the tank, thereby rapidly cooling the feed. At the same time, the multiple gas nozzles spray cooling air onto the feed during the mixing process, further improving the cooling effect and shortening the cooling time, thus achieving rapid cooling of the feed.

[0038] 3. The feed cooling equipment in this invention is equipped with a humidification module, which is used to humidify the cooling air, thereby humidifying the feed during cooling and increasing the feed moisture content from 8-9% to 10-11%, thus improving the input-output ratio of production.

[0039] 4. By setting inlet and outlet on the tank body, it is convenient to put feed into and discharge the cooling tank. At the same time, the bottom of the tank body is set as an inclined structure, and the outlet is set on the lower side of the bottom of the tank body, so that the feed is discharged more cleanly and thoroughly, avoiding the problem of contamination of the next batch of feed due to incomplete discharge of feed from the tank body.

[0040] 5. The top of the tank is equipped with an air vent, and a feed filter screen is installed inside the air vent. The air vent can balance the air pressure inside the tank and prevent the air pressure from becoming too high. The feed filter screen can prevent feed from leaking out of the air vent during the cooling process, thus avoiding feed waste.

[0041] 6. The gas jets from multiple gas nozzles are all directed toward the centerline of the tank, and the angle between the gas jet direction of each gas nozzle and the vertical direction is 30°~45°. The gas jets from multiple gas nozzles can blow air onto the feed during the mixing process, thereby increasing the contact area between the cooling air and the feed, further improving the cooling effect of the feed and shortening the cooling time.

[0042] 7. The feed cooling equipment in this invention is equipped with a filtration device, which filters out impurities and odors in the air, preventing impurities and odors in the air from entering the feed cooling tank and causing feed contamination, thereby improving the production quality of the feed.

[0043] 8. The cooling process of the feed cooling equipment in this invention is automated through a control module, eliminating the need for worker supervision and saving labor costs for production enterprises. Attached Figure Description

Detailed Implementation

[0051] The specific embodiments of the present invention are described below to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0052] like Figures 1-2 As shown, the present invention provides a feed cooling device, which includes multiple feed cooling tanks 1 and a cooling module. The cooling module is used to deliver cooling air to the multiple feed cooling tanks 1 to cool the feed inside the tank 101, thereby avoiding the occurrence of feed mold due to excessive internal temperature and extending the shelf life of the feed.

[0053] like Figure 2 As shown, specifically, as a specific arrangement of the feed cooling tank 1, each feed cooling tank 1 includes a tank body 101, and a stirring device 3 is provided on the tank body 101. The stirring device 3 includes a stirring motor 301 located at the bottom of the tank body 101. A stirring shaft 302 located inside the tank body 101 is connected to the output shaft of the stirring motor 301. The stirring shaft 302 is vertically arranged along the center line of the tank body 101, and multiple stirring blades 303 are spaced apart on the stirring shaft 302.

[0054] A cooling pipe 102 is fixedly installed on the inner wall of the tank 101. The cooling pipe 102 is spirally ascending along the height direction of the tank 101. The top of the cooling pipe 102 is a closed structure, and the bottom of the cooling pipe 102 passes through the tank wall of the tank 101 and is connected to the cooling module through a pipe. Multiple gas nozzles 4 are spaced apart on the cooling pipe 102.

[0055] During the feed cooling process, the stirring device 3 stirs the feed in the tank 101, which rapidly cools the feed inside; at the same time, multiple gas nozzles 4 spray cooling air onto the feed during stirring, further improving the cooling effect and shortening the cooling time, thus achieving rapid cooling of the feed.

[0056] The top of the tank 101 is provided with an air outlet channel 103, and a feed filter screen 5 is installed inside the air outlet channel 103. The air outlet channel 103 can balance the air pressure inside the tank 101 and prevent the air pressure in the tank 101 from becoming too high; the feed filter screen 5 can prevent feed from leaking out from the air outlet channel 103 during the feed cooling process, thus preventing feed waste.

[0057] Preferably, but not limited to, each tank 101 is provided with a feed inlet 104 at the top, through which feed enters the tank 101; the inner bottom surface of the tank 101 is inclined, and a discharge outlet 105 is provided at the bottom of the tank 101, located on the lower side of the inner bottom surface of the tank 101. The feed inlet 104 and the discharge outlet 105 facilitate the feeding and discharging of feed into and out of the cooling tank. Furthermore, by making the bottom of the tank 101 inclined and the discharge outlet 105 located on the lower side of the inner bottom surface of the tank 101, the feed is discharged more cleanly and thoroughly, avoiding the problem of contamination of the next batch of feed due to incomplete discharge from the tank 101.

[0058] As a preferred installation method for the gas nozzles 4, the gas injection direction of multiple gas nozzles 4 is all towards the centerline of the tank 101, and the angle between the gas injection direction of each gas nozzle 4 and the vertical direction is 30°~45°. The gas ejected from multiple gas nozzles 4 can achieve the effect of blowing air upward on the feed during the mixing process, thereby increasing the contact area between the cooling air and the feed, further improving the cooling effect of the feed and shortening the cooling time.

[0059] like Figure 1 As shown, as a specific configuration of the cooling module, the cooling module includes a blower assembly 201 and a cooling assembly 202 that are interconnected; the blower assembly 201 includes a blower, which is connected to the cooling assembly 202 through a pipe; the cooling assembly 202 is used to cool the air delivered by the blower and deliver the cooled air to the tank 101.

[0060] like Figure 4 As shown, in a specific configuration of the cooling assembly 202, the cooling assembly 202 includes a cooling cavity 2021. The two ends of the cooling cavity 2021 are connected to a blower and a cooling pipe 102 respectively through pipes. A vortex tube 2022 is provided on the cooling cavity 2021. A tangential inlet 2023 is provided on the wall of the vortex tube 2022, and the tangential inlet 2023 is connected to high-pressure gas. A hot air pipe 2024 and a cold air pipe 2025 are provided at both ends of the vortex tube 2022 respectively. The hot air pipe 2024 discharges the hot gas in the vortex tube 2022 to the outside. The cold air pipe 2025 has a curved spiral structure and is located on the outer wall of the cooling cavity 2021.

[0061] After the high-pressure gas enters the tangential inlet 2023 on the vortex tube 2022, the airflow generates a vortex and separates into two streams: a cold stream and a hot stream. The cold stream enters the cold air duct 2025 to cool the cooling chamber 2021 and the air inside it, while the hot stream can be led out to the outside through the hot air duct 2024. The cooling temperature of the cold air duct 2025 can be adjusted by regulating the flow rate of the high-pressure gas. The cold air duct 2025 has a curved spiral structure that winds around the outer wall of the cooling chamber 2021, increasing the contact area between the cold air duct 2025 and the outer wall of the cooling chamber 2021, thereby improving the cooling effect.

[0062] Specifically, such as Figure 1 and Figure 3 As shown, a filter device 6 is provided between the blower assembly 201 and the cooling assembly 202. The filter device 6 includes a filter box 601, and a filter layer 602 is provided inside the filter box 601. The filter layer 602 includes a quartz sand layer, an activated carbon layer and a filter element layer.

[0063] An installation notch 603 is provided on the outer wall of the filter box 601, and a fixing buckle 604 is provided at the corresponding position of the installation notch 603 in frontal view. The filter layer 602 passes through the installation notch 603 and is set inside the filter box 601. The bottom of the filter layer 602 is connected to the fixing buckle 604, thereby fixing the filter layer 602 to the filter box 601. The filtration device 6 filters impurities and odors in the air, preventing impurities and odors in the air from entering the feed cooling tank 1 and causing feed contamination, thus improving the production quality of the feed.

[0064] Specifically, such as Figure 1 and Figure 5 As shown, a humidification module 7 is provided between the cooling chamber 2021 and the tank 101. The humidification module 7 includes a humidification chamber 701, and a sealing partition 702 is provided inside the humidification chamber 701. The sealing partition 702 is used to divide the humidification chamber 701 into an upper chamber 703 and a lower chamber 704. The two sides of the upper chamber 703 are connected to the cooling chamber 2021 and the cooling pipe 102 respectively through pipes. The lower chamber 704 is filled with water, and an ultrasonic oscillating plate 705 is provided in the water. The ultrasonic oscillating plate 705 is used to oscillate the water into water mist. A mist outlet pipe 706 is provided on the sealing partition 702. The mist outlet pipe 706 is used to transport the water mist in the lower chamber 704 to the upper chamber 703.

[0065] The humidification module 7 is used to humidify the cooling air, thereby humidifying the feed during cooling and increasing the feed moisture content from 8-9% to 10-11%, thus improving the input-output ratio of production.

[0066] The feed cooling equipment also includes a control module, which includes a controller; a temperature sensor 2026 is installed inside the cooling chamber 2021; a humidity sensor 707 is installed inside the humidification chamber 701; the stirring motor 301, blower, ultrasonic vibrator 705, temperature sensor 2026, and humidity sensor 707 are all electrically connected to the controller; the cooling time of the feed cooling tank 1 is 3-5 hours, and the blower air volume is 20,000 m³ / h. 3 The cooling module maintains a cooling temperature of 8-10℃ per hour, while the humidification module 7 maintains an air humidity of 40-60%. The cooling process of the feed cooling equipment is automated through the control module, eliminating the need for worker supervision and saving labor costs for production enterprises.

[0067] The connection relationships and selection of electrical components in this solution are based on existing mature technologies, so the circuit structure and working principle between electrical components will not be described in detail here.

[0068] like Figure 6 As shown, the present invention also provides a cooling method for a feed cooling device, comprising:

[0069] Step 1: Ground preparation: Before installing the feed cooling equipment, prepare the ground in the feed workshop to ensure that the ground is level;
