Paper trays are the primary storage materials for eggs. During storage and transportation, these commodities face exposure to risks that lead to breakage. The paper tray production is an extensive process, thus a guarantee of safety for the items. The machine used to make them is the egg tray machine. It assumes a four-step procedure, each with a different role. Below is detailed information on how to make paper tray.
Pulping Stage
When learning how to make paper tray, the first step is pulping. This case refers to forming a mix of the two principal components, water and waste paper. Add appropriate amounts of the two in an empty location. An excessive of either can result in the mix being too runny or thick. The desirable state is a smooth and consistent mix. Otherwise, it wil result in substandard output. The system employs a pulp beater that executes the mixing task. It thoroughly beats up the components until the formation of mold in the right state. It is at this stage that you can decide to add pigmentation or additives. Egg trays come in varying types depending on the client’s preferences. Click here to know more about Beston Machinery.
Molding Stage
The second phase is the molding phase. The system features various machines, including different molds, a vacuum pump, and an air compressor. Once the mix is ready, pipes convey it to this stage. Upon arrival, the pipes discharge it on the awaiting forming molds. It is a continuous process until they cover the molds. The next step involves using the vacuum pump to suck the air out of the molds. The process is crucial as it also helps in getting rid of excess water. The last part is when the air compressor detaches the already formed paper tray from the mold by blowing air on them. During this stage, the operators can determine the quantity of production. Inspection is mandatory to remove the trays that are not in good shape. These rejects should never get to the clients.
Drying Stage
The drying stage of pulp egg tray making machine involves the complete removal of air from the molds. There are three different systems. However, before making a decision, it is vital to understand which of them works suitably in what set up. The first and most efficient options include metal or brick dryers. They come fitted with conveyor belts to allow for movements the even distribution of heat. They operate on either gas, electricity, or diesel. The two are quite costly as the sizes vary depending on your needs. The last option is sun-drying. It is cheap, but you have to check the forecast before you start production. It is also time-consuming.
Packaging Stage
Before packaging, the egg trays must go through the hot press. Its function is to eliminate any air spaces and give the trays a similar and defined shape. This step is vital since the operator can eliminate any egg trays that are not up to standard.
The above steps should enlighten you on how to make a paper tray. Each step relies on the previous, thus a need for attention to detail in all of them. More information on the egg crate making machine.
