Pulp Dryer Machine for Automatic Egg Tray Production Line

Egg tray generally refers to a packaging tool used to hold eggs, duck eggs and other eggs. Its main function is to absorb shock and facilitate transportation and carrying. According to the different production materials, it can be divided into pulp egg trays, plastic egg trays, etc. Among them, pulp egg trays are mostly made of recycled paper pulp and pressed by forming machines. Because of their simple production process, low cost and no environmental pollution, they are called “green” packaging and are the most common type of egg trays in our daily life. Most of the pulp egg trays used in the market are tray-mounted egg trays.

When actually processing the pulp egg tray, the process of drying the pulp egg tray pressed by the molding machine is very important, which directly affects the processing quality of the pulp egg tray. Nowadays, in order to increase the output of egg trays and reduce production costs, AGICO’s pulp dryer machine has a fully enclosed drying room, 360-degree uniform drying of materials, automatic operation, and no need for manual guards, which greatly increases output and improves product quality. AGICO’s pulp dryer machine is the drying equipment choice of many enterprises.

Civil engineering drying

The overall drying process of pulp dryer machine is not complicated. Our company can provide two drying methods, namely metal drying tunnel and concrete drying tunnel. These two pulp dryer machine materials are different, but the principle is basically the same, so we mainly talk about the principle.
The principle of drying is to heat the entire drying tunnel. Generally, a heating point is set in the middle part of the drying tunnel to heat the entire drying tunnel. The metal pulp dryer machine will use refractory steel materials, while the civil construction pulp dryer machine will use refractory steel. The main pulp dryer machine is made of refractory bricks, because the middle part will be heated all the time, so the temperature is very high, and the whole drying channel is heated by the flow of hot air, so as to achieve the purpose of drying. Generally speaking, it is like a civil construction drying kiln, and the length must be 50 or 60 meters. If the drying kiln is too short, it may cause the egg tray to go around the inside of the drying kiln and still not completely dry. This situation will effect egg tray drying efficiency and production efficiency.
Our company can provide a variety of heating methods for pulp dryer machine, such as coal heating (can not be used for metal pulp dryer machine), natural gas heating, electric heating, etc. The most economical is coal heating. However, considering the current environmental protection requirements, natural gas is recommended for heating because it is cost-effective and more importantly, it does not pollute the environment. From the point of view of heat consumption, compared with the heating efficiency of metal pulp dryer machine, the heating efficiency of concrete pulp dryer machine is higher, because the thermal conductivity of metal is much stronger than that of soil and stone, so there will be more dissipation in heat consumption. The more advantages of metal pulp dryer machine are in terms of neatness.
