Aquatic product drying machine and control method

Abstract

Disclosed is an aquatic product drying machine. The aquatic product drying machine comprises a feeding unit, a conveying unit and a microwave drying unit. The conveying unit comprises a first conveying belt and a second conveying belt, and a plurality of trays are placed on the first conveying belt. The feeding unit comprises a feeding funnel, a push plate, a feeding cylinder, a tray pushing cylinder, a first stopping cylinder and a tray base plate. The push plate is arranged at a lower opening of the feeding funnel. The feeding cylinder and the push plate are connected to be used for controlling the lower opening to be opened and closed. The tray base plate is arranged below the push plate. The first stopping cylinder is arranged between the tray base plate and the first conveying belt. The microwave drying unit is arranged on the second conveying belt and comprises a box body, a microwave generator, a capacitive sensor and a second stopping cylinder. The microwave generator is arranged inside the box body. The second stopping cylinder is arranged at an outlet of the box body. The capacitive sensor is arranged on a support corresponding to the second conveying belt and is used for detecting the reaching positions of the trays and sending signals to a control system, and thus the second stopping cylinder and the outlet of the box body are controlled to be opened and closed.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to an aquatic product dryer and a control method. Background technique [0002] Natural drying includes sunlight and air drying. Sunlight drying uses the heat energy generated by sunlight to evaporate the water contained in the product, and at the same time combines the wind factor to make the water vapor discharged from the aquatic product disappear into the air to achieve the effect of drying aquatic products; The wind force in the nature makes the air continuously blow over the surface of the aquatic products, taking away the water evaporated from the aquatic products to achieve the purpose of drying the aquatic products. This drying method is still the most widely used drying method so far due to almost no cost. [0003] This method depends on the natural climate conditions, the control level of the drying conditions is low, and the expected effect of the product cann...

AI Technical Summary

Problems solved by technology

[0003] This method depends on the natural climate conditions, the control level of the drying conditions is low, and the expected effect of the product cannot be guaranteed. After drying, the product index changes greatly, especially when the intensity of sunlight and air humidity cannot be controlled, the drying effect is extremely extreme. Low, not only can not guarantee the completion of drying on time, but also will cause uneven drying effect or even deterioration of the product

In addition, the hygienic conditions of the products are also difficult to be guaranteed.

[0004] Through the investigation of the drying results of aquatic products that currently use natural drying and other popular drying methods except microwave drying, it is found that these drying methods still used by most people have the following characteristics: natural methods cannot guarantee uncontrollable conditions such as weather and climate ;A variety of drying methods will lead to the destruction of the internal nutrients of aquatic products; long drying time and low efficiency; the interior of aquatic products is uneven after drying, and the effect is not up to standard; large consumption, high cost, and low economic benefit; different drying treatment methods Corresponding to different materials
