An egg tray machine relies on waste paper as its primary ingredient to make trays. It follows a four-fold manufacturing process that starts with mixing the raw materials and ending with dried trays on the other end of the machine. Egg tray machines come in manual, semi-automatic, and fully automatic variants. You should buy a fully automatic model as it has a higher output capacity. Here are some of the features of a fully automatic paper egg tray machinery.
• Production capacity
The production capacities of egg tray machines vary from 2000 to 6000 trays every hour. You should buy one depending on the demand for the number of egg trays in a week or month.
• Plant area
Most egg tray machines occupy at least 1500 m2. You can buy a bigger paper tray making machine if you want. The bigger machines are capable of delivering as many as 7500 trays in one hour.
• Tray weight
Egg trays shouldn’t weigh too much. A fully automatic egg tray machine produces trays that weigh approximately 70 to 75 grams. This weight is ideal. Manual machines make trays that weigh nearly 90 to 95 grams. Experts believe that this weight is heavier and not appropriate for eggs.
Egg tray machines go through a four-fold process while making the trays. Here are the steps involved:
1. First is the pulping stage. Here, you need to put all the ingredients in the machine. Pour appropriate quantities of water. The machine will shred the waste paper thoroughly and mix it with water to form a soft pulp. It creates a muddy mixture that is not too hard or too soft. This helps the next part of the machine to give shape to the trays. Detailed egg tray machine project report for you.
2. The next part pumps the slurry mixture into a dice to give shape in the molding process. Vacuum absorption and negative pressure force the mixture to form crates that look like egg trays. But this part only produces a single layer of the mold. The final tray consists of multiple layers so that they become thick enough to hold the eggs safely. Most machines provide egg tray molds. You can also buy molds separately if you want to make customized trays.
3. The penultimate stage involves drying the trays. There is a drying line where the semi-finished trays go through a heater that dries the trays together. Fully automatic machines can dry as many as 3000 to 4000 trays in one batch. Drying is a crucial process as it helps in maintaining the shape of the trays. Otherwise, the wet trays may bend or break if you handle them manually before drying.
4. The last stage involves hot pressing the trays before sending them out. This helps the user to pack the trays with eggs according to the way he/she wants.
You should buy a fully automatic egg tray manufacturing machine as it doesn’t require too much labor costs. The initial price may be high but these machines last for decades. Plus, they are easy to use. Even an amateur can handle the controls without requiring a lot of experience.
