[0022] The mesh numbers of the screen 3, the first screen plate 5 and the second screen plate 6 are 6 mesh, 10 mesh and 30 mesh respectively.

[0023] As shown in the drawings, Figure 1 In this embodiment, the device integrating the feeding system, the pre-separation zone, the main separation zone, the winnowing system and the collection system. The pre-separation zone separates the insect bodies and larger bran, and the main separation zone combined with the sorting system is the main area for collecting insect exuviae.

[0024] Specifically, it comprises: The feeding system: an open feeding hopper 2 (40 cm × 40 cm × 10 cm) is equipped with an adjusting valve (adjusting plate) to control the rate of insect bodies, insect exuviae and other materials entering and ensure uniform input.

[0025] The pre-separation zone: the pre-separation zone is a nylon screen 3 with an inclination of 25° to 30° to reduce damage to the insects; the insect bodies and larger bran are preliminarily separated through the inclined screen 3, and after the screening is completed, they slide down the slope of the first feeding plate 4 to the first collection box 8 (40 cm × 60 cm × 10 cm) due to gravity, and the substances passing through the inclined screen 3 reach the main separation zone; The main separation zone: the main separation zone adopts a double-layer screen plate structure composed of the first screen plate 5 and the second screen plate 6, which are 10 mesh and 30 mesh respectively; the insect exuviae are blown by the fan into the fourth collection box 11 (40 cm × 60 cm × 10 cm) below during the process of falling from the screen 3 to the first screen plate 5 and falling on the first screen plate 5 due to their light texture; the bran with heavy texture falls on the first screen plate 5 of 10 mesh and falls into the second collection box 9 through the second feeding plate 12; the substances passing through the first screen plate 5 of 10 mesh are small bran, insect exuviae and insect sand, and the small bran falls on the second screen plate 6 of 30 mesh and falls into the second collection box 9 through the second feeding plate 12.

EMBODIMENT

[0028] The device for separating insect exuviae in the growth process of yellow mealworms provided by the application comprises a feeding system, a pre-separation zone, a main separation zone, a winnowing system and a collection system, and the device as a whole has a box-shaped structure. The feeding system is located at the top of the device and is provided with a feeding hopper 2 with a size of 40cm*40cm*10cm and equipped with an adjusting valve (adjusting plate) for controlling the rate of insect bodies, insect exuviae and other materials entering and ensuring uniform input. The separation zone is located below the feeding system and comprises a sieve net 3, a first sieve plate 5 and a second sieve plate 6, all of which are arranged at an inclination with an inclination angle of 25°-30°. The mesh sizes of the sieve net 3, the first sieve plate 5 and the second sieve plate 6 are 6 mesh, 10 mesh and 30 mesh respectively, which are used for preliminary separation of insect bodies, bran and insect sand respectively. The collection system is located at the bottom of the device and is provided with four collection boxes, namely a first collection box 8, a second collection box 9, a third collection box 10 and a fourth collection box 11, all of which have a size of 40cm*60cm*10cm and are used for collecting insect bodies, bran, insect sand and insect exuviae respectively.

[0029] In this embodiment, a first feeding plate 4 is arranged between the separation zone and the collection system for preliminary separation of insect bodies and larger bran. Large insects slide along the first feeding plate 4 into the first collection box 8, and the remaining materials fall into the main separation zone. The first sieve plate 5 and the second sieve plate 6 are respectively connected to a second feeding plate 12 and a third feeding plate 13, which respectively fall medium insects, small insects and bran into the second collection box 9 and insect sand into the third collection box 10. In addition, a fan mounting rack 7 is arranged below the first feeding plate 4, and a fan is fixedly installed on the fan mounting rack 7. The fan is opposite to the first sieve plate 5 and is used for blowing light insect exuviae into the fourth collection box 11. The overall structure of the device is compact, the combination of wind screening and nylon sieve nets reduces the damage of simple mechanical machines to insect exuviae and improves the separation efficiency of insect exuviae; batch processing and accurate control make the entire separation process fast and efficient, the separation effect is multiple and ideal, and the production efficiency is significantly improved.

[0030] The separation operation steps of the present embodiment are as follows: prepare a total mass of 50 g of Tenebrio molitor and exuviae mixture (100 live Tenebrio molitor, 20 g of exuviae, and the rest of bran and insect sand), and uniformly feed the device through the feeding hopper 2. Adjust the feeding speed to control the preliminary separation of the material on the screen 3. At this stage, most of the insect bodies (about 90%) are separated and slide into the first collection box 8 along the first feeding plate 4, which takes 1 minute 5 seconds. The remaining material falls into the first screen plate 5, and the fan is started. This stage is the main separation stage. The exuviae are blown to the fourth collection box 11 opposite the fan due to their light texture, and the medium and small insects, heavier bran and insect sand fall into the second and third collection boxes respectively due to gravity. The total time spent in the main separation zone is 2 minutes 13 seconds, as shown in Figure 2

[0031] After the separation is completed, each collection box is taken out, and the material is weighed and the insect bodies are counted. The first collection box collects 98 live Tenebrio molitor, and the total mass of the insect bodies is 13.2 g. After inspection, the insect bodies are active, and there is no obvious mechanical damage such as broken limbs and damaged body wall. The fourth collection box collects 18.8 g of exuviae. The second collection box collects 12.3 g of bran, with 2 live Tenebrio molitor mixed in. The third collection box collects 5.7 g of insect sand, and no live Tenebrio molitor is found.

[0032] According to the above data, the key performance indicators are calculated as follows: Insect body survival rate: the total number of recovered live insects = 98 (first collection box) + 2 (second collection box) = 100. Insect body survival rate = (100 / 100) x 100% = 100%.

[0033] Exuviae recovery rate: recovered exuviae mass = 18.8 g. Exuviae recovery rate = (18.8 / 20) x 100% = 94%.

[0034] Efficiency improvement rate: under the premise of completing the same unit of work (processing 50 g of mixture), the required manual time is reduced from 8 minutes 28 seconds (508 seconds) per person to 2 minutes 13 seconds (133 seconds) per person, and the efficiency improvement rate = [(508-133) / 508] x 100% ≈ 73.8%.

[0035] ​The device realizes efficient separation of tenebrio molitor, insect exuviae, bran and insect sand. The insect exuviae recovery rate is as high as 94%, proving the effectiveness of the combination of winnowing and multi-layer screening; the survival rate of insect bodies reaches 100%, and the insect bodies are complete after separation, which is significantly better than the traditional mechanical screening method; the whole separation process is fast and continuous, and compared with the traditional manual screening, the efficiency is improved by 73.8%. The device structure is simple, the operation is continuous, and it is suitable for insect exuviae recycling treatment in large-scale tenebrio molitor breeding, greatly improving the efficiency of insect exuviae recycling in tenebrio molitor breeding, and the insect sand is completely separated, cleaning the tenebrio molitor breeding environment; different sizes of tenebrio molitor are preliminarily separated, which is convenient for classified feeding, also reduces the harm to tenebrio molitor in the screening process, and fully proves that the device has high application value and economy in large-scale tenebrio molitor breeding.
