Description

Dryer control system after forming machine tool processing

The present invention relates to a control system for dryers following the processing of forming machines, in particular to a control system for dryers suitable for feed (for example: fish, shrimp, pet feed) and food (for example: dried fruit, vegetarian material), In particular, it has the advantages of saving energy and time, increasing production capacity and improving profits.

Generally, there are many types of products that need to be dried, but the more difficult ones are aquatic feed, vegetarian materials, dried fruits and other products that require more precise humidity control, because the product humidity is too high and it is easy to mold, and if it is too dry, the product will be too hard and In addition to poor quality, the weight is also reduced. If the unit price is high, too dry will not only reduce the quality, but also reduce the weight (too much water evaporates), which will greatly reduce the profit. The industry has to A matter of careful consideration; taking aquatic feed as an example, please refer to Figure 8, the forming machine tool 70 includes an extrusion conditioning machine 71 and a granulator 72, all of which mix water 90,901 and materials 91,911 in the extrusion conditioning In the quality machine 71 or the granulator 72, after internal stirring, extrusion or granulation, the semi-finished products 711,721 to be dried are produced, and then transported to the dryer 80; the more advanced dryer 80 is vertical Cylindrical structure, inside the housing 801 is provided with a longitudinal rotating shaft 802, the rotating shaft 802 is provided with a multi-layer storage tray 82, the top of the dryer 80 is provided with a material inlet 81; The semi-finished products 711 and 721 to be dried are poured in from the material inlet 81, and a temperature is roughly set by the temperature controller 84, and the air is passed from the bottom of the dryer 80. The hot air enters upwards, so that the semi-finished products 711, 721 to be dried placed from the top of the dryer 80 can evenly fall on the multi-layer storage tray 82, and the storage tray 82 carrying the semi-finished products 711, 721 to be dried is rotated by the central rotating shaft 802, but every When the storage tray 82 of one layer is rotated to a specific position, it is overturned (not shown) by the turning mechanism, and the semi-finished products 711, 721 to be dried on the storage tray 82 are dropped into the storage tray 82 of the next layer, so that The dried semi-finished products 711,721 fall layer by layer to the bottom (exit) of the dryer 80, and because the continuous hot air blows from bottom to top, it can take away the moisture of the semi-finished products 711,721 to be dried until they fall to the bottom of the dryer 80, and are dried. The final product 83 was released.

However, this seemingly simple action is actually not easy to operate, and the following shortcomings often occur:

1. The forming machine 70 includes an extrusion conditioning machine 71 and a granulator 72. Generally speaking, the extrusion conditioning machine 71 needs more water 90 (the ratio is about 15-20%) to perform extrusion. The granulator 72 is just the opposite; therefore, different semi-finished products to be dried 711, 721 to the dryer 80 need to have different temperature control and the amount of hot gas output. The drying of the next product can only be carried out after complete completion, so the continuity of the manufacturing process is affected, and a lot of time and cost are wasted for each test.

2. Even if you use the best dryers on the market, the actual drying effect can only be achieved by trial and error. At the beginning, you should roughly grasp the temperature and the amount of hot air for drying, and wait until it is dry. After the first finished product 83 in the machine is produced, it is tested to know whether the last adjustment parameters are correct; All of them are not up to the standard, but they cannot be cleared out immediately. We can only continue to add materials and re-adjust the temperature control and air supply volume. I don’t know when the finished product will be produced for the second time, or it can only be produced. Sampling based on experience or waiting a little longer is a waste; Sometimes the more times the adjustment is made, the more confusing the information will be, and the temperature or air intake will be easily confused, so the operation is very difficult.

3. Due to the repeated temperature control and heat intake, a lot of materials and heat energy are wasted, and it takes a long time, so the cost remains high.

4. Because the operation of the dryer 80 requires multiple trials and errors, each time the forming machine 70 must manufacture more semi-finished products for the test of the dryer 80, resulting in too much waste. At the same time, different types, such as: Switching between shrimp feed and fish feed drying processes, as well as the production of large quantities and small quantities, all produce different temperature and airflow parameters, which cause many troubles for operators.

The main purpose of the present invention is to adopt a control system with a visual aid function. When the semi-finished products released by molding machines (for example: extrusion machines, granulators, etc.) The direction information is displayed on the screen after calculation, and can be assisted by the time axis of the change point and a variety of control information. The dried product is the main feature of the present invention.

In order to achieve the above-mentioned purpose, the specific implementation of the present invention can be achieved in the following manner: the present invention is arranged after the operation of the relevant molding machine tool in use, and before entering the dryer operation; mainly it is provided with: a vertical Dryer, the top and top of the dryer are respectively provided with a material inlet and a material outlet, and a rotating shaft is arranged in the longitudinal direction of the dryer, and a multi-layer storage tray is arranged on the rotating shaft. fall on the multi-layer storage tray one by one, being blown by hot air or cold The wind blows from bottom to top for drying; a measurement unit is installed in front of the feed inlet of the dryer, and the measurement unit is used to detect the moisture content and energy consumption information of the raw materials from the molding machine; a data processing unit receives Measure the information of the unit, and use the big data database to estimate the temperature and steam volume required by the dryer for the current raw material drying; a screen control unit with multiple function keys and a record image inside the dryer, the The internal recording image system is equipped with an array marking group; the array marking group is composed of a plurality of marking keys, and each marking key represents a storage tray at a relative position inside the dryer, and the marking key is moved as the storage tray moves. It is also relatively moved and rearranged relative to the array marking group; a temperature control and air intake device, which is regulated by the screen control unit and injects the airflow of the set temperature into the vertical dryer for drying. A humidity sensor, which is installed at the discharge port of the dryer, measures it immediately when the object to be dried comes out of the discharge port of the dryer, and measures it immediately when the object to be dried does not meet the humidity requirements for drying. The data is sent to the data processing unit for calculation, and then the screen control unit corrects the set parameters and adjusts the dryer until it reaches the drying standard. This can reduce the waste of materials, simplify the process of drying trial and error and time, and save energy and production costs.
