What are the advantages of egg tray machines

 The molding quality of rotary egg tray machines can be categorized as good, poor, or very poor, with the classification standard being the degree of homogenization of the egg trays or the uniform distribution of fibers. A new type of pulp egg tray machine is a general term for pulp egg tray machines used for long-distance egg transportation. It mainly consists of a forming machine, a hydraulic pulper, a vacuum dewatering machine, an air compressor, and a drying oven. Today, let’s take a look at the advantages of the new type of pulp egg tray machine. The primary drying energy source used for pulp selection production in the new pulp egg tray machine can be diesel or natural gas. Customers can choose the more cost-effective option based on the local prices of these energy sources. Coal or heavy oil can also be used, but this would require the use of steam or thermal boilers, which would increase the equipment’s investment cost and footprint. The rotary egg tray machine mainly comprises the pulp molding system, pulp forming system, pulp drying system, and auxiliary systems. The storage and flow of pulp in the pulping system, as well as the molding structure and...

The main purpose of egg tray machine

Egg trays are typically used to hold eggs such as chicken and duck eggs. Their primary functions are shock absorption and ease of transport and handling. Based on the manufacturing material, egg trays can be divided into pulp egg trays and plastic egg trays. Depending on the number of eggs they hold, they can be classified as single egg trays or carton egg trays. Pulp egg trays are mostly made from recycled paper pulp through molding machines. Due to their simple manufacturing process, low cost, and environmental friendliness, they are referred to as “green” packaging and are the most common type of egg trays we use daily. The machines that produce egg trays are called egg tray machines, which are used to manufacture pulp egg trays for long-distance transportation of eggs. The main components of egg tray machines include molding machines, hydraulic pulpers, vacuum dewatering machines, air compressors, and drying ovens. Molding machines are divided into four types: reciprocating, single-side suction, four-side rotating, and eight-side rotating. Hydraulic pulpers are categorized into vertical and horizontal types. Vacuum dewatering machines are classified into three types: Roots vacuum pumps, water ring vacuum pumps, and Roots blowers. Air compressors used are piston air compressors....

How to ensure the quality of egg tray production equipment

  The temperature in the drying channel of the egg tray machine can usually reach 105-200 degrees Celsius. No matter which drying equipment is selected, the equipment itself is required to have a good insulation layer to prevent heat loss, and the structure of the equipment should be able to ensure that the temperature of the internal components is uniform. There are currently two main methods for obtaining hot air. One is to directly generate hot air by burning in a hot air furnace. The other is to use steam to generate hot air through heat exchange and air heat exchange. Hot air is used as a drying medium in the drying channel, and the heat source can be coal, fuel oil or natural gas. Therefore, to ensure the quality of egg tray production equipment, special attention should be paid to raw materials at this time. Only by ensuring the quality and safety of raw materials can you finally get the product and make full use of them. Most people do not guarantee the safety of raw materials, which may lead to unqualified overall quality. It is necessary to pay extra attention to that since the egg tray will shape...

The relationship between mold and finished product

  Pulp molding utilizes molding molds to shape pulp slurry into paper molded products, with molds being crucial to this technique. It is commonly used to produce disposable fast food boxes, bowls, and trays, which have simple shapes and utilize molds and products that are somewhat standardized. However, for industrial packaging and other applications, pulp molding involves larger variations in product dimensions and more complex and diverse shapes, necessitating bespoke molds for each design. Therefore, mold design and production are integral throughout the product manufacturing process.   The molding process for pulp molded products differs significantly from that of rubber and plastic products in the mold cavity. Pulp molded products are formed using a slurry containing approximately 1% fiber in a water solution. During forming, most of the water must be removed, requiring molds to be meshed. The molding process involves the slurry depositing a certain thickness onto a mesh mold, necessitating formation on the surface of a single convex or concave mesh mold. As the product forms, it also acts as a filtering process, with thicker sections decreasing filtration performance and forming speed. Thus, regardless of the complexity of the product shape, the thickness of pulp molded products uniformly...

What should you pay attention to when using an egg tray machine?

 When using an egg tray machine, you need to pay attention to the following matters: The egg tray machine should be placed on a stable ground to ensure the normal operation and service life of the machine. Before operating the egg tray machine, you need to check whether the power connection is firm to avoid accidents caused by power problems. When operating the egg tray machine, you should pay attention to the operation of the machine. If any abnormality or malfunction is found, stop the machine immediately for inspection to avoid greater damage. The lubrication of the egg tray machine is very important. The machine should be lubricated and maintained regularly to ensure the smooth operation and stability of the machine. When repairing or replacing parts of the egg tray machine, the power supply should be disconnected first to ensure safe operation. When the machine is running, it is prohibited to place hands or other objects near the running parts of the machine to avoid injury. The area around the egg tray machine should be kept clean and tidy to avoid debris and water stains to ensure the safe use of the machine. In short, when using an egg tray...

The operation process of egg tray machine

 The process of egg tray production by egg tray machine is roughly divided into： Pulping: Put the waste paper into the pulper and stir it into pulp; Debugging: Add the required additives to the pulp and adjust the pulp to the appropriate concentration; Molding: Pump the pulp into the molding machine and squeeze it through the mold Form a wet base; drying: put the wet base into a dryer to heat and dry to evaporate the water; shaping: adjust some irregular-looking egg trays with a shaping machine; storage: bundle the finished egg trays and put them away Into the warehouse. These steps seem simple, but while it is simple, it also has unknown technological content.
