Why mealworm feeding is so popular now?

Mealworms are protein-rich insect larvae. Its edible value, economic value, and medicinal value are very high. According to detect proving, dry yellow mealworm contains adipose 30%, contains protein to be as high as 50% above, and it also contain in addition phosphorus, potassium, iron, na, aluminum wait for constant element and a variety of microelement.

The mealworm can be used for feeding fish, birds and other kinds of animals. And it can also be processed for making high-quality mealworm powder which is very popular on the market for making all kinds of animal feed.

Why use the mealworm separator machine for screening?

During the mealworm breeding process, there often occurs a "dead insect" phenomenon, at this point, the dead mealworm should be removed from the bulk mealworms in order to avoid influence on live mealworms. But for separating the dead worms from live worms, the traditional manual screening for picking out the dead worms one by one is very inefficient and will take a lot of time.

The special sieving machine for yellow mealworm can quickly produce larva and dead mealworm, greatly reduce the mortality rate of yellow mealworm caused by screening, and can distinguish four different body sizes of finished insects, large, medium and small insects. The screen box of the machine is easy to split, easy to collect and clean the remaining yellow mealworm in the box, high efficiency, greatly reduce the cost of the artificial screen.

Working principle of the mealworm separator machine

The mealworm automatic screening device is provided with an open bracket at the upper end, and a sieve which can be directly taken up and down is placed in the bracket through a pressure spring. The sieve includes an upper screen and a lower screen arranged relatively. The upper screen and the lower screen are arranged tilting along the same side. The bottom of the lower screen is equipped with a vibrating motor through the connecting plate.

On both sides of the bracket, one left and one right are equipped with drainage grooves protruding from the sidewall of the bracket to collect the larvae after screening. When this mealworm sorting machine is working, it will sieve out the larvae slung and skins, dead and damaged mealworms continuously and then grade the mealworms into four levels based on the mealworm size.

Factors affecting screening rate of mealworm and methods of adjustment

The same mealworm screening machine is operated by different people, in different environments, the cleaning rate, and efficiency will be very different because the selection is live insects, so the adjustment should be flexible, in order to give full play to the machine's maximum effect.

1. Temperature factor: when the temperature is lower than 25℃, the crawling ability of the yellow mealworm will be greatly reduced. When the mealworm sorting machine runs, healthy insects will directly fall into the dead insects and pupae, which will affect the cleaning rate.

Suggestion: try to operate in the greenhouse.

2. Human factors: the amount of insects is too fast or too slow so that mealworms pile up on the conveyor belt.

Suggestion: evenly adjust the pest amount

3. Group potential factors: the group potential of yellow mealworm of different farmers is different, the group potential is strong and the selection is clean, otherwise the selection is poor (similar to the situation of different temperatures).

Suggestion: adjust the screen plate at the bottom of the upper and lower conveyor belt.
