Abstract

This invention discloses a continuous insect rearing system and method, including several rearing tanks, insect feed inlet and outlet devices, water supply and air supply devices, etc. Water is supplied from the middle rearing tank upwards and downwards, forming two independent water supply channels; air is supplied from the bottom rearing tank upwards and exhausted after passing through the top rearing tank. One type of water storage device for the rearing tank includes a water flow channel plate with several parallel grooves, installed under the horizontal plate of the tank body along with water distribution pipes on both sides, and connected to a water inlet via the water distribution pipes. The water inlet, water distribution pipes, water flow channel plate, and horizontal plate form several independent water flow channels. The reverse air supply design of this invention allows for rapid drying of the bottom layer material and prevents the upper layer food from drying too quickly, thus reducing larval consumption. Cooling water enters from the middle and exits from the top and bottom layers, effectively removing heat generated in the middle rearing tank while simultaneously heating the top and bottom rearing tanks, improving larval activity in the top rearing tank and accelerating moisture evaporation from the bottom rearing tank.

Description

Technical Field

[0001] This invention relates to an insect breeding tank and breeding system, as well as a continuous breeding method, belonging to the field of insect breeding technology. Background Technology

[0002] Insect larvae can feed on livestock manure and kitchen waste, producing high-value insect protein feed. Due to their rapid reproduction, wide range of dietary habits, high conversion rate, ease of management, low feeding costs, and good palatability, they are widely used in the treatment of kitchen waste and livestock manure. However, the high energy consumption required for specific environmental conditions in the artificial breeding of insect larvae restricts the rapid development of the industry.

[0003] In the process of insect larvae breeding, it is very important to effectively adjust the breeding temperature and humidity through heat exchange devices to meet the breeding requirements of insects. Conventional air circulation methods to regulate the material temperature have the following problems: (1) Using hot and cold air to control the breeding environment temperature results in large breeding equipment and high energy consumption; (2) During the heating and cooling process, the air flow is frequent, which will cause large changes in the humidity of the material, making the material unsuitable for insect breeding and thus reducing breeding efficiency. Water, due to its high specific heat, is often used as an excellent heat conductor. Announcement No. CN221710937U, Patent Name: A water-heated insect breeding device and its system, heats and cools the material through heat exchange tubes. The water and material in the heat exchange tubes are separated by multiple layers of material, which affects heat conduction; Announcement No. CN210113967U, Patent Name: A black soldier fly breeding device, regulates the temperature through a heat conductor in the outer pool. The amount of heat conductor is large, the temperature regulation is slow, and uneven temperature is easy to occur.

[0004] In addition, insect larvae farming currently mainly includes ground farming and vertical farming. Vertical farming has received widespread attention due to its high space utilization rate, but it places higher demands on the temperature and humidity control of the farming system. Summary of the Invention

[0005] Based on the problems in the prior art, the present invention provides an insect breeding tank that solves the problems of high energy consumption and uneven temperature caused by adjusting the material temperature in existing insect breeding equipment. At the same time, the present invention also provides a continuous insect breeding system and method, which provides an effective method for controlling the temperature and humidity environment and reduces energy consumption and environmental control costs.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions.

[0007] This invention first provides a continuous insect rearing system, comprising:

[0008] A breeding box includes: a main frame, a bottom plate and side plates fixed on the main frame, and a top plate that overlaps and is fixed on the top of the side plates. The bottom plate, side plates and top plate form a breeding box with openings at the front and back, and the main frame supports the entire box.

[0009] Several layers of breeding tanks are set inside the breeding box; each layer of breeding tank includes a feed transfer device and a water storage device;

[0010] The feed transfer device consists of front and rear support plates, a driving roller, a driven roller, and a conveyor belt. The driving and driven rollers are fixed to both sides of the support plates via bearing seats, and the distance between the driving roller and the end face of the support plate is 10–160 cm greater than the distance between the driven roller and the other end face of the support plate. The end face of the support plate refers to the contact surface between the breeding trough and the side plates of the breeding box when the trough is installed. The conveyor belt is installed on the driving and driven rollers. Furthermore, the conveyor belt is porous or mesh-shaped, with mesh sizes ranging from 1 to 50 mm.

[0011] The water storage device is a sealed water tank with a water inlet at each end of the front side for water inflow and outflow. The water tank is positioned below the conveyor belt of the feed conveyor, with the conveyor belt flush against the top surface of the water tank. The top surface of the water tank is smooth and flat to ensure smooth operation of the conveyor belt. The front and rear sides of the water tank are fixed to or integrally formed with the support plate of the feed conveyor. Furthermore, reinforcing ribs are installed inside the water tank to enhance its load-bearing capacity. The water tank height is 10–100 mm.

[0012] Several layers of aquaculture troughs are arranged in a staggered manner along the length direction, where the length direction refers to the vertical direction from one side panel of the aquaculture box to the other side panel; the staggered arrangement means that in two adjacent aquaculture troughs, the active roller of one layer and the driven roller of the other layer are located on the same side of the aquaculture box.

[0013] The aquaculture system also includes two drive motors; the active rollers of each aquaculture tank at intervals are mechanically connected to one of the drive motors through sprockets and chains, so that the transmission belts of each two adjacent aquaculture tanks run in opposite directions.

[0014] The aquaculture system also includes several connecting water pipes for connecting the water storage devices of adjacent layers. The connection method is as follows: the system is divided into upper and lower groups, with the middle aquaculture tank within the aquaculture box as the boundary. The water storage devices in the two groups of tanks are connected by connecting water pipes to form two unidirectional water flow channels. Specifically, the water inlet at the driven roller end of the lowest layer of the upper group's aquaculture tank serves as the water inlet for the upper group's aquaculture tank, connecting to an external water supply device. The connecting water pipes connect the water inlet at the active roller end of the lowest layer of the aquaculture tank in this group to the water inlet at the driven roller end of the adjacent layer above, and so on upwards. The two water inlets at the top layer of the aquaculture tank... One water inlet connects to the water storage device of the lower breeding tank, and the other serves as the water outlet of the upper breeding tank, connecting to an external water outlet. The lower breeding tank adopts the same connection method, with the water inlet at the driven roller end of the uppermost breeding tank serving as the water inlet of the lower breeding tank, connecting to an external water supply device. The connecting water pipe connects the water inlet at the active roller end of the uppermost breeding tank to the water inlet at the driven roller end of the adjacent lower breeding tank, and so on downwards. One of the two water inlets of the bottommost breeding tank connects to the water storage device of the upper breeding tank, and the other serves as the water outlet of the lower breeding tank, connecting to an external water outlet.

[0015] The breeding system also includes a feeding port, a larvae feeding port, and a discharge port respectively installed on the breeding box; wherein, the feeding port and the larvae feeding port are installed on the top plate of the breeding box, at the corresponding position at one end of the driven roller of the top breeding trough; the discharge port is installed on the bottom plate of the breeding box, at the corresponding position at one end of the active roller of the bottom breeding trough.

[0016] The breeding system also includes air inlets and exhaust outlets respectively installed on the side panels of the breeding box; wherein, the air inlet is located on the side panel near the feed outlet, in the channel between the bottom breeding trough and the next layer of breeding trough; the exhaust outlet is located on the side panel near the feed inlet, in the channel between the top breeding trough and the top panel of the breeding box; thus, a bottom-up air supply system is formed in the closed breeding space enclosed by the side panels, top panel of the breeding box and the side panels of each layer of breeding troughs, which is opposite to the direction of insect feed transmission.

[0017] The aquaculture system also includes baffles for several aquaculture troughs installed on the side panels of the aquaculture tank. The baffles are installed on the side panels above the driven rollers of each aquaculture trough. The baffles are sealed to the inner wall of the side panels near the driven rollers to prevent materials from falling into the gap between the driven rollers and the water tank, and to prevent the lower airflow from passing through both sides of the driven rollers to enter the upper layer, thus preventing airflow short circuit.

[0018] Furthermore, a feeding port is provided on the side plate near the driven roller end of each layer of breeding tank to enable multiple feedings.

[0019] Furthermore, the outside of the breeding tank is covered with an insulation layer to reduce energy loss.

[0020] Furthermore, observation windows are installed on the support plates of each breeding tank to observe the growth of the insects.

[0021] The water storage device for each layer of the aquaculture tank in the above-mentioned aquaculture system can also be configured as follows: The water storage device includes a tank body, a water flow channel plate, water inlets, and water distribution pipes. The tank body is composed of a horizontal plate, a front plate, and a rear plate, and can be formed by splicing multiple pieces of material or by bending them into a single piece. The water flow channel plate is installed on the lower surface of the horizontal plate of the tank body and is tightly connected to it. The water distribution pipes are installed on the lower surface of the horizontal plate of the tank body, located at both ends along the length of the water flow channel plate. A water inlet is provided on each side of the front plate of the tank body, respectively connected to the water distribution pipes at both ends.

[0022] More specifically, the water flow channel plate has a structure with several parallel grooves, which can be wavy or corrugated, etc.; the upper surface of the water flow channel plate is closely connected to the lower surface of the tank body horizontal plate, and the extension direction of the parallel grooves is consistent with the length direction, and it is installed below the tank body horizontal plate; in this way, in each layer of breeding tank, two water inlets, water distribution pipes, water flow channel plates, and tank body horizontal plates form several independent water flow channels.

[0023] The front and rear plates of the water storage device are fixed to the support plate of the insect feed conveying device or integrally formed with the support plate. The water storage device is located below the conveyor belt of the insect feed conveying device. The conveyor belt is attached to the upper surface of the horizontal plate of the water storage device. The upper surface of the horizontal plate of the water storage device is smooth and flat to ensure that the conveyor belt attached to it runs smoothly.

[0024] Furthermore, a support member may be provided at the bottom of the water flow channel plate.

[0025] This invention provides a method for continuous insect rearing, employing the aforementioned continuous insect rearing system, and includes the following steps:

[0026] (1) Determine the insect rearing time, divide the rearing time into days, and obtain the number of divisions;

[0027] (2) Obtain the total effective length of the transmission belt after deducting the portion covered by the baffles from all transmission belts;

[0028] (3) Divide the total effective length of the transmission belt according to the obtained number of divisions to obtain the daily advance length of the transmission belt;

[0029] (4) Start the drive motor to drive the conveyor belt. Insect food and larvae are distributed on the conveyor belt through the feeding port and larvae feeding port. Stop the drive motor when the length of the distributed food reaches the daily advance length of the conveyor belt.

[0030] (5) Water at 20-35 degrees Celsius is introduced through the inlets of the upper and lower breeding tanks respectively to control the temperature of the feed in the breeding tanks and provide the temperature conditions for rapid growth of larvae. After passing through each water storage device, the water is discharged from the outlets of the top and bottom layers respectively.

[0031] (6) Dry air at 20-35 degrees Celsius after treatment is introduced through the air inlet, passes through each layer of breeding tank in the opposite direction of the conveyor belt, and is discharged through the exhaust outlet.

[0032] (7) One day later, repeat step (4), and the food and larvae given on the previous day will be transferred to the conveyor belt that advances the next day, and the original position will be replaced by new food and larvae.

[0033] (8) Repeat step (4) every day until the larvae put in on the first day are discharged from the outlet after a feeding cycle.

[0034] Then, the process of step (4) and the discharge process is repeated once a day to achieve continuous material feeding and discharge.

[0035] This invention also provides another mode of continuous insect rearing method, using the above-mentioned continuous insect rearing system, including the following steps:

[0036] (1) Determine the insect rearing time;

[0037] (2) Obtain the total effective length of the transmission belt after deducting the portion covered by the baffles from all transmission belts;

[0038] (3) Divide the total effective length of the conveyor belt by the feeding time to obtain the forward speed of the conveyor belt;

[0039] (4) Start the drive motor and drive the conveyor belt at the obtained forward speed to continuously and evenly add insect food and larvae;

[0040] (5) Water at 20-35 degrees Celsius is introduced through the inlets of the upper and lower breeding tanks respectively to control the temperature of the feed in the breeding tanks and provide the temperature conditions for rapid growth of larvae. After passing through each water storage device, the water is discharged from the outlets of the top and bottom layers respectively.

[0041] (6) Dry air at 20-35 degrees Celsius after treatment is introduced through the air inlet, passes through each layer of breeding tank in the opposite direction of the conveyor belt, and is discharged through the exhaust outlet.

[0042] (7) After a feeding cycle, the discharge port begins to discharge continuously.

[0043] This invention also provides an insect breeding tank, comprising a tank body, a water flow channel plate, water inlets, and water distribution pipes. The tank body is composed of a horizontal plate, a front plate, and a rear plate. The water flow channel plate has a structure with several parallel grooves, installed on the lower surface of the horizontal plate of the tank body. The upper surface of the water flow channel plate is tightly connected to the lower surface of the horizontal plate of the tank body, and the extension direction of the parallel grooves is perpendicular to the front or rear plate of the tank body. The water distribution pipes are installed on the lower surface of the horizontal plate of the tank body, located at both ends of the water flow channel plate, and connected to the water flow channel plate. A water inlet is provided on each side of the front plate of the tank body, respectively connected to the water distribution pipes at both ends. Thus, the two water inlets, the water distribution pipes, the water flow channel plate, and the horizontal plate of the tank body form several independent water flow channels. When breeding insects, the insect larvae are placed on the upper surface of the horizontal plate of the tank body for breeding.

[0044] The present invention also provides an insect breeding system, which includes at least a plurality of the above-mentioned insect breeding tanks and a larval transport mesh belt, wherein the larval transport mesh belt is arranged close to the upper surface of the cross plate of the tank; during breeding, the insect larvae are arranged on the transport mesh belt.

[0045] This invention achieves the following beneficial effects:

[0046] 1) Insect feed and larvae enter from the top breeding tank and are transported by a conveyor belt to the bottom breeding tank for complete rearing and discharge. During this process, the feed and larvae pass through multiple breeding tanks. Each time they pass through a tank, the feed and larvae are turned over, preventing the feed from clumping and allowing it to be quickly consumed by the larvae. This also makes the material looser, drier, and easier to sieve.

[0047] 2) The porous mesh belt allows the feed to make better contact with the water tank while being transported, accelerating the heat transfer between the feed and the water tank, thus making it easier to control the temperature.

[0048] 3) Dry air enters from the bottom rearing tank and exits in the reverse direction to the top rearing tank. This allows the bottom material to dry quickly, ensuring the air is moist by the time it reaches the top, preventing the feed in the upper rearing tank from drying out too quickly and reducing larval consumption. Furthermore, it significantly increases the moisture content of the incoming and outgoing air, thereby drastically reducing ventilation volume and lowering environmental control costs.

[0049] 4) Cooling water enters from the middle breeding tank and exits from the top and bottom tanks in two directions. While effectively removing the heat generated in the middle breeding tank, it also heats the top and bottom breeding tanks, improving the activity of larvae in the top breeding tank and accelerating the evaporation of moisture in the material in the bottom breeding tank.

[0050] 5) For aquaculture tanks using water flow channel plates, the water flow channel plates are tightly connected to the horizontal plates of the tank body of the water storage device. This not only greatly improves the strength of the horizontal plates of the tank body and reduces the material used in the tank body, but also greatly improves the pressure-bearing capacity of the multiple small water flow channels formed by the water flow channel plates and the horizontal plates of the tank body, thereby accelerating the water flow speed and enhancing the heat exchange effect.

Detailed Implementation

[0059] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0060] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0061] Example 1

[0062] like Figure 1-2 The diagram shown is a three-dimensional structural schematic of the continuous insect rearing system of this embodiment from two different angles. Figure 3 A three-dimensional partial sectional diagram of the aquaculture system, and Figure 4 A partial sectional view of the three-dimensional aquaculture trough shows that the continuous aquaculture system includes a main frame 1, several layers of aquaculture troughs 2, a top plate 3, a bottom plate 4, side plates 5, a drive motor 6, and connecting water pipes 7, all mounted on the main frame 1. In this embodiment, six layers of aquaculture troughs 2 are used, but the actual number of layers can be adjusted as needed. The driving roller 201 and driven roller 202 are mounted on the support plate 205 via bearing seats 207, and the conveyor belt 203 is mounted on the driving roller 201 and driven roller 202. A water tank 204 is positioned between the conveyor belts 203 of the upper and lower aquaculture layers, with the conveyor belt 203 fitting flush with the top surface of the water tank 204 of that aquaculture layer. Water inlets 208 are located at both ends of the side of the support plate, and the water tank contains reinforcing ribs 206. The support plate 205 is equipped with… Observation window 209; Top plate 3 is installed on the upper part of the topmost breeding tank 2, and the top plate 3 is provided with a feeding port 301 and a larvae feeding port 302, which are located at one end of the driven roller of the topmost breeding tank 2; Bottom plate 4 is installed at the bottom of the water tank 204 of the bottommost breeding tank 2, and the bottom plate 4 is provided with a discharge port 401, which is located directly below the active roller of the bottommost breeding tank; Side plates 5 are installed at both ends of the breeding tank 2, and are connected to the support plate. 205, top plate 3, and bottom plate 4 form a closed breeding space; air inlet 501 is set on the side plate at one end of the discharge port 401; exhaust port 502 is set on the side plate at one end of the feeding port 301; a baffle 503 is provided above the driven roller 202, and the baffle 503 is tightly connected to the adjacent side plate 5 to prevent materials from falling into the gap between the driven roller 202 and the water tank 204, and to prevent lower layer gas from passing through both sides of the driven roller 202 to enter the upper layer, forming an airflow short circuit; from top to bottom, feeding ports 504 are set above the driven roller 202 of the second, fourth, and sixth breeding tanks 2 to realize multiple feedings; the active roller 201 on every other layer of breeding tank 2 is mechanically connected to the drive motor 6 through the sprocket 8 and chain 9, so that the power output by the drive motor 6 is transmitted to each active roller 201. In this embodiment, two drive motors 6 are set, and the two drive motors 6 rotate in opposite directions.

[0063] From top to bottom, the first, second, and third breeding tanks 2 form one group, and the fourth, fifth, and sixth breeding tanks 2 form another group, each connected to a water pipe. The water inlets 208 of adjacent breeding tanks 2 are connected together. Finally, each of the first, third, fourth, and sixth breeding tanks 2 leaves one water inlet 208 to connect to the external water pipe, forming two independent water flow channels, the upper group and the lower group.

[0064] When using the continuous culture system of this embodiment for insect culture, the following steps are performed:

[0065] Set the motor speed and turn on the motor to drive the active roller 201 to rotate;

[0066] Insect food and larvae are continuously fed onto the conveyor belt 203 of the top-level breeding tank 2 through the feeding port 301 and the larvae feeding port 302, respectively. The active roller 201 drives the material on the conveyor belt 203 to move on the water tank 204. After passing through the active roller 201, the material falls into the next breeding tank.

[0067] The conveyor belt 203 on the lower breeding tank 2 continues to carry the material in the opposite direction to the material movement of the upper layer. The material moves layer by layer and is eventually discharged continuously from the discharge port 401.

[0068] Meanwhile, water at 20-35 degrees Celsius is introduced into the water inlets 208 on the third and fourth breeding tanks 2 to cool down the feed in the second, third, fourth and fifth breeding tanks. As the water temperature gradually rises, the water flowing through the first breeding tank 2 heats up the feed in the tank, increasing the activity of the larvae; the water flowing through the sixth breeding tank heats up the material in the tank, accelerating the evaporation of moisture in the material.

[0069] Meanwhile, the treated dry air enters the bottom breeding tank 2 through the air inlet, carrying away the evaporated moisture, and enters the upper breeding tank. Layer by layer, it moves in the opposite direction to the material movement direction and is finally discharged from the exhaust port to the waste gas treatment device.

The water flow channel plate 104 is installed on the lower surface of the horizontal plate 101 and is tightly connected to the horizontal plate 101. The water distribution pipes 105 are installed on the lower surface of the horizontal plate 101 and at both ends of the water flow channel plate 104. Two water inlets 208 are respectively located at one end of the water distribution pipes 105 on both sides, and the water inlets 208 are connected to an external water supply device. In this embodiment, the tank body is integrally bent and formed; in this embodiment, the cross-section of the water flow channel plate 104 is wavy, and a support member 106 is provided at the bottom.

[0074] When using the breeding tank of this embodiment for insect breeding, the larvae are placed on the upper surface of the horizontal plate of the tank for breeding. The two water inlets 208 are connected to the external water supply device, with water entering on one side and exiting on the other. Together with the water distribution pipe 105, the water flow channel plate 104, and the horizontal plate of the tank 101, they form several closed water flow channels to provide temperature regulation for the breeding tank.

[0075] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention.
