Modern equipment and types of raw materials for the production of toilet paper

Toilet paper is one of the most important household items of a civilized person. Millions of rolls of this indispensable product are produced and used every day around the world. Not every entrepreneur knows how toilet paper is made. Meanwhile, the production of such a necessary hygiene product is one of the most promising investments.

Types of toilet paper

Rolled toilet paper appeared at the end of the 19th century and at first caused ridicule and embarrassment among the townsfolk. The demand for its production has increased significantly with the growth of population and the development of civilization. Modern toilet paper is significantly different from its progenitor and can be of several types:

Depending on the feedstock:

• gray - made from waste paper (grades МС1, МС3, МС3, МС7 - cardboard, МС10 - newspapers);
• white - made of cellulose.

By number of layers:

• single layer;
• two-layer;
• multilayer (three or more layers).

Regardless of the grade, toilet paper must be strong, soft, highly hygroscopic and break into fibers when it enters the water. For its decoration, you can use only eco-friendly and neutral dyes that do not cause allergic reactions.

Production stages

The paper production process consists of several stages:

1. Preparation of raw materials. Waste paper is cleaned of impurities, crushed in special crushers, mixed with water and filtered through a sieve that traps the remaining foreign objects.
2. Preparation of water-paper mixture. The paper pulp is washed in a large amount of water and ground in a mill to a fine fraction. Then poured into a concentration stabilizer and adjusted to 0.5%.
3. Drying. The resulting mixture is poured onto a conveyor mesh, along which it is directed to a drying drum. During the passage through the line, excess water drains and is sent to the flushing stage. In the drum, the paper mass dries, is cut into sheets and rolled into reels.
4. Formation of rolls. The bobbins are unwound, embossed and the required number of layers are applied to the paper, and then rolled into rolls of the required diameter.
5. Packing and calibration. Large rolls are labeled and cut into several small ones.

At the stage of formation, the paper can be dyed or applied with a decorative pattern on top with the manufacturer's logo.

Production equipment

It is impossible to complete the entire papermaking process with a single machine, so manufacturers install special lines or mini-factories. They consist of pulper, mixing tanks, paper machine, unwinder and cutter.

Pulper

A vertical cylindrical bath with blades in which waste paper with a small amount of water is broken into fibers and passes through a sieve of a certain caliber. The device is intended for grinding and purification of raw materials from impurities. Its capacity depends on the size and can reach up to 500 tons per day.

Mixing tanks

For the production of paper, several tanks of different volumes are used, in which a water-paper mixture of a certain concentration is gradually prepared. In the first container, the slurry cleared of impurities is washed with a large amount of flowing and reverse (flush from the grid line) water, and ground to a fine fraction. The quality and price of the final product depends on the degree of purity. The resulting mixture enters the pressure tank and passes into the concentration stabilizer, where it is brought to a consistency of 0.5% of the mixture with water.

paper machine

The main element of the entire production, where the process of turning paper pulp into a complete canvas takes place. It consists of a mesh table, a press, an inlet device, dryer drums and a reel. From the tanks, the water-paper mixture enters a moving screen table, from which the liquid flows down and is pumped out by vacuum pumps into a special tank for further use in washing.

The pressed mass is pressed to remove residual moisture, after which it becomes dense and transparent. The raw material enters a cylindrical drying drum, where it is dried with hot steam under pressure up to 40% humidity at 10 revolutions per minute. The finished canvas is cut with a scraper knife and rolled into reels.

Bobbin unwinder

A device for forming toilet paper of a given diameter. The bobbins are unwound, embossed and patterned on the surface, and the canvas is wound on a cardboard core or directly into a roll.

Slicing device

At the final stage of production, the wound paper web is cut into small rolls with a diameter of 80 to 200 mm. Thanks to specially sharpened band knives, the productivity of the machine can reach up to 1200 units/hour.

The production of toilet paper is an uncomplicated and cost-effective enterprise. It does not require a lot of resources and, with the right organization of sales, quickly pays off.
