The aquaculture species in China are constantly innovating with the development of the times, and the output is also increasing. The research and application of aquaculture production and automated management technology are also receiving more and more attention. In order to ensure the water environment, it is of great significance to supervise and control the water in the culture environment and improve the growth of aquatic organisms and the development of the aquaculture industry. The application of sensor technology, wireless communication technology, and embedded technology in aquaculture production and management control has enhanced the ability to automatically monitor the water quality of the aquaculture environment, and improved the production efficiency and economic efficiency of the aquaculture industry. The on-line monitoring of water quality by the aquaculture monitoring system requires the collection and transmission of data and the provision of an interface to facilitate inquiries. It also needs to meet the requirements of low cost and low energy consumption. Add WeChat, you want to have:
Principle of Plate Dryer
Wet raw materials are fed continuously on the first hot plate on the top of dryer. Raw materials then will be turned and agitated under the function of rotating rake. When on the small hot plate, raw material will moving to plate outer edge and drop down from the outer edge of the big hot plate underneath, then will moving inner-ward and drop down from its central hole to the small hot plate on the lower layer. Both small and large drying plates are arranged alternately so that raw material can go through the whole dryer continuously. Dried product will drop from the lowest layer of hot plate to the bottom layer of the chamber body, and will be moved by rakes to discharging port. The moisture will be removed from the moisture discharging port on top of chamber, or sucked out by vacuum pump (only for vacuum type hot plate dryer).
Advantages of plate dryer
1. Easy production operation, good adaptability.
(1) User can obtaining the best drying effect by adjusting thickness of raw material pavement, shaft rotating speed, quantity and form of rakes.

Each monitoring node of the aquaculture monitoring system collects the water quality parameter data of the monitoring point through a sensor, and converts it into a corresponding weak voltage signal. After being adjusted to a standard voltage by a conditioning circuit, it is sent to the microcontroller through its built-in A/D converter. Converted to the corresponding digital voltage value, the converted digital signal is calculated and processed to obtain the actual parameter value. Then the data is transmitted to the monitoring master station in real time through the RF module.
A large number of test experiments have proved that the embedded aquaculture monitoring system has strong self-organizing ability of the network. The real-time and reliability of the system meets the actual needs, and the water quality parameters such as the pH and dissolved oxygen in the culture environment can be performed for 24 hours. Real-time monitoring. The application of embedded technology in aquaculture processes has improved the performance of aquaculture monitoring systems, and the functionality is easily extended. 
(2) Each layer of hot plate could be filled in heating medium or cooling medium for drying or cooling.
(3) Retention time of material can be accurately controlled.
2. Convenient operation
(1) Operation panel is simple to use.
(2) A thorough discharging could be finished very soon after stop feeding
(3) Inspect the whole drying process or dryer washing process via observation window
3. Low energy consumption
(1) The driven motor of dryer consumes very less power.
(2) Drying through indirect heating, which has high efficiency.
4. Friendly operation environment, solvent can be recovered.
(1) Air speed and air volume in drying chamber is very less, powder material is barely blow up.
(2) There has very big range of moisture content between bottom hot plate layer and top hot plate layer, dried powder product which located at bottom layers is far from exhausting vent, wet material which located at top layers has large bulk density. It makes powder barely out.
