Description

Technical Field

[0001] This utility model relates to the field of quick-freezing technology, and in particular to an ultra-low temperature fluidized bed quick-freezing machine. Background Technology

[0002] A quick-freezing machine is a highly efficient freezing device that can freeze a large number of products in a short time. It can effectively and economically freeze a variety of products placed inside the quick-freezing machine.

[0003] Authorization Announcement No.: CN212902175U discloses a fluidized bed freezer, including a freezer body, a conveying section and a refrigeration section placed inside the freezer body, and a baffle plate installed between the conveying section and the refrigeration section; the freezer body has an inlet and an outlet on both sides, and the inlet and outlet on the outside of the freezer body have an inlet end and an outlet end; characterized in that the inlet end has an inlet rack, and the outlet end has an outlet rack; the conveying section is arranged along the length direction of the freezer body and includes a support; a first drive roller rotatably installed at the inlet rack end and a second drive roller at the outlet rack end; a closed conveyor belt that sequentially passes through the first drive roller, the support, and the second drive roller; a first drive device that drives the drive roller to rotate; and a vibration component is also provided on the support, the support is located below the conveyor belt, the vibration component includes multiple shafts, multiple rollers connected to the eccentric shafts of the shafts are provided on the shafts, and a second drive device that drives the shafts to rotate.

[0004] Existing quick-freezing machines have the following shortcomings:

[0005] First, the entire storage unit has only one temperature zone, lacking a multi-temperature design, resulting in poor freezing effect and efficiency. The single conveyor belt design without multi-temperature zones cannot meet diverse freezing requirements, preventing materials from reaching their optimal state during freezing and affecting the quality and taste of food.

[0006] Secondly, the cold air circulation in existing quick-freezing machines typically only passes through the evaporator once. This design results in unsatisfactory heat exchange, making it impossible to reach lower temperatures and thus failing to meet the needs of quick-freezing scenarios requiring even lower temperatures. For some foods with stringent low-temperature requirements, such as certain high-end seafood and special ingredients, the existing cold air heat exchange method cannot achieve rapid and efficient quick-freezing, thereby affecting the shelf life and quality of the food.

[0007] Third, the interconnected arrangement of multiple fans results in significant air friction resistance. The fans must overcome considerable resistance to propel airflow during operation, leading to high energy consumption. This not only increases operating costs but also contradicts the principles of energy conservation and environmental protection. In today's increasingly energy-constrained environment, reducing equipment energy consumption has become an urgent issue. Utility Model Content

[0008] The purpose of this invention is to provide an ultra-low temperature fluidized bed freezer to solve the problems of poor freezing effect and efficiency, unsatisfactory cold air heat exchange effect and high fan energy consumption in existing fluidized bed freezers.

[0009] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0010] A cryogenic fluidized bed freezer includes an insulated chamber, which has a longitudinal partition that divides the chamber into a precooling section and a cryogenic deep freezing section, which are arranged on the left and right sides.

[0011] Both the precooling section and the ultra-low temperature deep freezing section are equipped with transverse partitions, which divide the precooling section and the ultra-low temperature deep freezing section into a freezing chamber and a heat exchange chamber set at the front and back, respectively.

[0012] The freezer compartment is equipped with a horizontally arranged conveyor belt, and the conveyor belt in the precooling section extends above one end of the conveyor belt in the ultra-low temperature deep freezing section;

[0013] The heat exchange chamber is equipped with a heat exchange and air supply assembly.

[0014] The present invention is further configured such that: the conveyor belt includes a stainless steel spring wire mesh belt, the stainless steel spring wire mesh belt is made of food-grade stainless steel, and the mesh size of the stainless steel spring wire mesh belt is smaller than the particle size of the material to be frozen; the mesh size allows airflow to easily enter from the bottom to the top of the stainless steel spring wire mesh belt, thereby causing the material on the stainless steel wire mesh belt to tumble, which can make the material cool more evenly and quickly, and can also prevent the material from clumping; a number of rods are sleeved on the stainless steel spring wire mesh belt and are linearly and evenly distributed along the long side of the belt, the ends of the rods are fixed on the chain A, and the chain A is driven by multiple sprockets A;

[0015] The upper half of the stainless steel spring wire mesh belt is equipped with a pulse chain-beating device. The pulse chain-beating device can also prevent materials from sticking to the stainless steel spring wire mesh belt by striking it.

[0016] The present invention is further configured as follows: the pulse chain striking device includes multiple chain striking base shafts, which are linearly arranged below the upper half of the stainless steel spring wire mesh belt and rotatably connected to the frame of the insulation chamber. Multiple chain striking bases are fixed on the chain striking base shafts and arranged axially along the chain striking base shafts. Multiple chain striking short shafts are fixed on the outside of the chain striking bases and are evenly distributed around the circumference of the chain striking base shafts. The chain striking short shafts can intermittently strike the stainless steel spring wire mesh belt as the chain striking base shafts rotate. A sprocket B is fixedly connected to the chain striking base shafts. The sprockets B on the multiple chain striking base shafts are connected by a chain B, and the chain B is connected to a power mechanism that drives the transmission.

[0017] The present invention is further configured such that: the front end of the conveyor belt in the precooling section is provided with an ice-melting and drying mechanism;

[0018] The ice-melting and drying mechanism includes an ice-melting chamber located at the front of the insulated storage unit. The ice-melting chamber contains a heater, which can be an electric heater or a steam heater. A drying fan is positioned above the ice-melting chamber, facing the stainless steel wire mesh belt. The stainless steel wire mesh belt in the pre-cooling section passes through the ice-melting chamber and is heated by the electric heater inside, melting the ice crystals solidified on the belt. The drying fan then dries and cleans the surface of the belt. After drying, the belt moves to the upper section for placing materials. If the stainless steel wire mesh belt is not heated and dried, the low temperature will cause it to absorb moisture and impurities from the ambient temperature environment, contaminating the belt. Heating and drying with air ensures the cleanliness of the stainless steel wire mesh belt, improving the quality of frozen foods.

[0019] The present invention is further configured such that: the heat exchange air supply assembly includes a primary heat exchange evaporator and a secondary heat exchange evaporator fixedly disposed in the heat exchange chamber, the primary heat exchange evaporator being stacked on top of the secondary heat exchange evaporator, and a partition being fixedly disposed at the junction of the primary heat exchange evaporator and the secondary heat exchange evaporator; the primary heat exchange evaporator, the secondary heat exchange evaporator and the partition divide the heat exchange chamber into an air inlet chamber, a ventilation chamber and an air outlet chamber, and a fan is disposed in the air outlet chamber;

[0020] The upper section of the conveyor belt divides the freezer compartment into a freezer chamber and an air supply chamber arranged vertically, and the fan is connected to the air supply chamber;

[0021] The transverse partition is equipped with a vent that connects the freezing chamber and the air inlet chamber.

[0022] The heat exchange and air supply assembly circulates the cold air passing through the conveyor belt, thereby freezing the materials on the conveyor belt. The circulation principle of the heat exchange and air supply assembly is as follows: the cold air, after cooling the materials in the freezing chamber, enters the inlet chamber through the vents. Then, the cold air in the inlet chamber passes through the primary heat exchange evaporator and enters the ventilation chamber. The cold air in the ventilation chamber then passes through the secondary heat exchange evaporator and enters the outlet chamber. A fan then blows the cold air from the outlet chamber into the supply chamber. The cold air in the supply chamber, powered by the fan, is blown upwards and passes through the conveyor belt into the freezing chamber, thus completing the cold air circulation. By passing through the primary and secondary heat exchange evaporators, the circulating cold air undergoes two heat exchanges, resulting in an even lower temperature after heat exchange. This significantly reduces the quick-freezing time, improves the quick-freezing effect, and increases the quick-freezing efficiency of the materials.

[0023] The present invention is further configured such that: a baffle is provided between two adjacent fans, and the baffle runs through the air outlet cavity and the air supply cavity;

[0024] Multiple baffles and the inner walls of the air outlet and supply chambers form multiple independent air ducts, each of which is connected to a corresponding fan. By setting up multiple independent air ducts, interference between fans can be reduced, air friction can be decreased, unnecessary energy consumption can be avoided, and thus the overall energy consumption of the entire equipment can be reduced.

[0025] The present invention is further configured such that the insulated warehouse body is formed by multiple insulated panels;

[0026] The insulation board includes a stainless steel surface layer and a polyurethane insulation layer sandwiched between the stainless steel surface layers;

[0027] The insulation board is 120-150 mm thick, which provides excellent insulation and reduces the loss of cold energy inside the insulation shell.

[0028] The present invention is further configured such that the primary heat exchange evaporator and the secondary heat exchange evaporator are vertical structures and are variable fin spacing evaporators, thereby ensuring that the evaporator does not frost or clog during long-term operation in a low-temperature environment, has better heat exchange effect, and does not accumulate debris.

[0029] The present invention is further configured such that the working temperature of the freezing chamber in the pre-cooling section is -42 to -35 ℃;

[0030] The working temperature of the freezing chamber in the ultra-low temperature deep freezing section is -65 to -55 ℃, which can meet the quick-freezing requirements of various materials.

[0031] The present invention is further configured such that: multiple longitudinal partitions are provided, and the multiple longitudinal partitions divide the insulated warehouse into multiple temperature zones, which can meet the quick-freezing requirements of different materials.

[0032] The outstanding effect of this utility model is:

[0033] Compared with existing technologies, the temperature zone design improves freezing effect and efficiency: the insulated warehouse is divided into a pre-cooling section and an ultra-low temperature deep freezing section by a longitudinal partition. The pre-cooling section can pre-cool the materials, and the ultra-low temperature deep freezing section can freeze the materials more quickly. Freezing in different temperature zones greatly improves freezing effect and efficiency, and ensures the quality and taste of food.

[0034] Double heat exchange reduces quick-freezing time: The primary and secondary heat exchange evaporators in the heat exchange air supply assembly perform two heat exchanges on the circulating cold air, resulting in a lower temperature of the cold air after the heat exchange. This significantly reduces quick-freezing time and improves the quick-freezing effect. For foods that require rapid freezing, it can better preserve their nutritional components and original quality. At the same time, it also improves the quick-freezing efficiency of materials and increases the equipment's capacity.

[0035] Independent air ducts reduce energy consumption: Baffles are installed between adjacent fans to form independent air ducts, which reduces turbulence between fans, reduces air friction, avoids unnecessary energy consumption, and thus reduces the overall energy consumption of the whole equipment.

[0036] The conveyor belt is designed to ensure the quality of material cooling: the conveyor belt is made of stainless steel spring wire mesh, and its mesh design facilitates airflow to make the material tumble, resulting in more uniform and rapid cooling and preventing material from clumping; at the same time, the pulse chain-breaking device effectively prevents the material from sticking to the stainless steel spring wire mesh, ensuring the quality of material freezing.

[0037] The ice-melting and drying mechanism ensures the cleanliness of the conveyor belt: The ice-melting and drying mechanism at the front end of the pre-cooling section conveyor belt, through the action of heating and drying fans, ensures the cleanliness of the stainless steel spring wire mesh belt, avoids food contamination due to the conveyor belt adsorbing water vapor and impurities, and improves the quality of frozen food.

[0051] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0052] The following is for reference Figures 1 to 7 The embodiments of this utility model are described below:

[0053] A type of ultra-low temperature fluidized bed freezer, such as Figure 1 , Figure 2 As shown, it includes an insulated storage body 1, and the insulated storage body 1 is provided with a longitudinal partition 11, which divides the insulated storage body 1 into a pre-cooling section 101 and an ultra-low temperature deep freezing section 102 arranged on the left and right.

[0054] Both the precooling section 101 and the ultra-low temperature deep freezing section 102 are provided with transverse partitions 12, which divide the precooling section 101 and the ultra-low temperature deep freezing section 102 into a freezing chamber 103 and a heat exchange chamber 104 arranged in front and behind, respectively.

[0055] The freezer compartment 103 is equipped with a horizontally arranged conveyor belt 2, and the conveyor belt 2 in the precooling section 101 extends above one end of the conveyor belt 2 in the ultra-low temperature deep freezing section 102;

[0056] The heat exchange chamber 104 is equipped with a heat exchange and air supply assembly 4.

[0057] Conveyor belt structure such as Figure 4 , Figure 5 , Figure 6 As shown, the conveyor belt 2 includes a stainless steel spring wire mesh belt 21. The stainless steel spring wire mesh belt 21 is made of food-grade stainless steel. The mesh size of the stainless steel spring wire mesh belt 21 is smaller than the particle size of the material to be frozen. The mesh size allows airflow to easily enter from the bottom to the top of the stainless steel spring wire mesh belt, thereby causing the material on the stainless steel wire mesh belt to tumble, which can make the material cool more evenly and quickly, and can also prevent the material from clumping. Several rods are linearly and evenly distributed along the long side of the belt and sleeved on the stainless steel spring wire mesh belt 21. The ends of the rods are fixed to the chain A, and the chain A is driven by multiple sprockets A.

[0058] The upper half of the stainless steel spring wire mesh belt 21 is equipped with a pulse chain-beating device. The pulse chain-beating device can also prevent materials from sticking to the stainless steel spring wire mesh belt by striking it.

[0059] The pulse chain-beating device includes multiple chain-beating base shafts 22, which are linearly arranged below the upper half of the stainless steel spring wire mesh belt 21 and rotatably connected to the frame of the insulation chamber 1. Multiple chain-beating bases 23 are fixed on the chain-beating base shafts 22 and arranged along the axial direction of the chain-beating base shafts 22. Multiple chain-beating short shafts 24 are evenly distributed around the circumference of the chain-beating base shafts 22 and are fixed to the outside of the chain-beating bases 23. The chain-beating short shafts 24 can intermittently strike the stainless steel spring wire mesh belt 21 as the chain-beating base shafts 22 rotate. The chain-beating base shafts 22 are fixedly connected to sprockets B, and the sprockets B on the multiple chain-beating base shafts 22 are connected by chains B. The chains B are connected to a power mechanism that drives the transmission.

[0060] Ice melting and drying mechanism 3 Figure 7 As shown, the conveyor belt 2 in the precooling section 101 is equipped with an ice-melting and drying mechanism 3 at its front end;

[0061] The ice-melting and drying mechanism 3 includes an ice-melting chamber 31 located at the front of the insulated storage unit 1. The ice-melting chamber 31 contains a heater, which can be an electric heater or a steam heater. A drying fan 32 is located above the ice-melting chamber 31, facing the stainless steel spring wire mesh belt 21. The stainless steel spring wire mesh belt 21 in the pre-cooling section passes through the ice-melting chamber and is heated by the electric heater inside, melting the ice crystals solidified on it. The drying fan then dries and cleans the surface of the stainless steel spring wire mesh belt. After drying, the stainless steel spring wire mesh belt moves to the upper section for placing materials. If the stainless steel spring wire mesh belt and ice crystals are not heated and dried, the low temperature will cause it to easily absorb moisture and impurities from the ambient temperature environment, thus contaminating the belt. Heating, drying, and blowing air ensure the cleanliness of the stainless steel spring wire mesh belt and improve the quality of frozen foods.

[0062] Heat exchange air supply components such as Figure 2 As shown, the heat exchange air supply assembly 4 includes a primary heat exchange evaporator 41 and a secondary heat exchange evaporator 42 fixedly installed in the heat exchange chamber 104. The primary heat exchange evaporator 41 is stacked on top of the secondary heat exchange evaporator 42. A partition 43 is fixedly installed at the junction of the primary heat exchange evaporator 41 and the secondary heat exchange evaporator 42. The primary heat exchange evaporator 41, the secondary heat exchange evaporator 42 and the partition 43 divide the heat exchange chamber 104 into an air inlet chamber 105, a ventilation chamber 106 and an air outlet chamber 107. A fan 44 is installed in the air outlet chamber 107.

[0063] The upper half of the conveyor belt 2 divides the freezer compartment 103 into a freezer chamber 108 and an air supply chamber 109 arranged vertically, and the fan 44 is connected to the air supply chamber 109;

[0064] The transverse partition 12 is provided with a vent 121 that connects the freezing chamber 108 and the air inlet chamber 105.

[0065] The heat exchange and air supply assembly circulates the cold air passing through the conveyor belt, thereby freezing the materials on the conveyor belt. The circulation principle of the heat exchange and air supply assembly is as follows: the cold air cooled in the freezing chamber 108 enters the air inlet chamber 105 through the vent 121. Then, the cold air in the air inlet chamber passes through the primary heat exchange evaporator and enters the ventilation chamber 106. The cold air in the ventilation chamber then passes through the secondary heat exchange evaporator and enters the air outlet chamber 107. The fan 44 then blows the cold air from the air outlet chamber into the air supply chamber. The cold air in the air supply chamber is blown upwards by the fan and passes through the conveyor belt into the freezing chamber 108, thus completing the cold air circulation. The circulating cold air undergoes two heat exchanges through the primary and secondary heat exchange evaporators, resulting in a lower temperature after heat exchange, significantly reducing the quick-freezing time, improving the quick-freezing effect, and increasing the quick-freezing efficiency of the materials.

[0066] Independent wind pool Figure 4 As shown, a baffle 45 is provided between two adjacent fans 44, and the baffle 45 runs through the air outlet cavity 107 and the air supply cavity 109.

[0067] Multiple baffles 45 and the inner walls of the air outlet cavity 107 and air supply cavity 109 form multiple independent air ducts 400, each of which is connected to a corresponding fan 44. By setting up multiple independent air ducts, interference between fans can be reduced, air friction can be reduced, unnecessary energy consumption can be avoided, thereby reducing the overall energy consumption of the entire equipment.

[0068] like Figure 2 As shown, the insulated warehouse body 1 is enclosed by multiple insulation panels 13;

[0069] Insulation board 13 includes a stainless steel surface layer and a polyurethane insulation layer sandwiched between the stainless steel surface layers;

[0070] The insulation board 13 has a thickness of 120-150 mm, which provides excellent insulation and reduces the loss of cold energy inside the insulation shell.

[0071] As a preferred option, the primary heat exchange evaporator 41 and the secondary heat exchange evaporator 42 are vertical structures and are variable fin spacing evaporators, thereby ensuring that the evaporators do not frost or clog during long-term operation in low-temperature environments, have better heat exchange effects, and do not accumulate debris.

[0072] Preferably, the operating temperature of the freezing compartment 103 in the precooling section 101 is -42 to -35 ℃;

[0073] The working temperature of the freezing chamber 103 in the ultra-low temperature deep freezing section 102 is -65 to -55 ℃, which can meet the quick-freezing requirements of various materials.

[0074] Preferably, multiple longitudinal partitions 11 are provided, which divide the insulated storage chamber 1 into multiple temperature zones, which can meet the quick-freezing requirements of different materials.

[0075] Working principle: Material 9 is placed on the stainless steel spring wire mesh belt 21 of the conveyor belt 2 in the pre-cooling section 101. As the conveyor belt moves to the right, the material first enters the freezing chamber of the pre-cooling section for preliminary freezing. After pre-cooling, the material enters the conveyor belt of the ultra-low temperature freezing section and enters the freezing chamber of the ultra-low temperature deep freezing section for further deep freezing. During the freezing process, the heat exchange air supply assembly starts to work. The cold air after the freezing chamber cools the material enters the air inlet chamber through the vent, and then passes through the primary heat exchange evaporator and the secondary heat exchange evaporator in sequence before entering the air outlet chamber. The fan sends the cold air into the air supply chamber. Under the power of the fan, the cold air is blown upward and passes through the conveyor belt into the freezing chamber, completing the circulation of cold air.

[0076] During the precooling and animal freezing processes, the pulse chain beater continuously strikes the corresponding stainless steel spring wire mesh belt to prevent materials from sticking to the wire mesh. At the same time, the blowing of cold air can also keep the materials on the stainless steel spring wire mesh belt in a "boiling" state.

[0077] The cold air, having undergone two heat exchanges, is at an even lower temperature, enabling rapid and efficient freezing of materials, thus improving the quick-freezing effect and efficiency. Simultaneously, the independent air duct reduces turbulence and energy consumption between the fans, ensuring stable equipment operation.

[0078] In the pre-cooling section, the ice-melting and drying mechanism melts and dries the passing stainless steel spring wire mesh belt to ensure its cleanliness.

[0079] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
