Wax Water Coating

The wax on the surface of the fruit is divided into two categories: one is the natural wax on the surface of the fruit itself, which is secreted by the plant itself, which can effectively avoid the rapid loss of moisture of the fruit and prevent external microorganisms, pesticides and other invasion of the pulp, play a protective role, harmless to the human body. The other type is artificial waxing of fruits. The main purpose is to preserve freshness and antiseptic.

Fruit waxing is mainly for good sales, taking oranges as an example, the surface of the freshly picked oranges have dust, generally the fruit farmer will first clean and then wax through the machine, so that the fruit sells well, the selling price is also high. Many fruits are waxed.

RELAB's spray waxing nozzle, using a small diaphragm pump, sprays 40~100 micron wax mist under a pressure of 10~15 bar, evenly covering the surface of the fruit, and then polished by felt, the wax forms a protective film on the surface, which can not only protect the skin of the fruit, improve the gloss, but also prevent the evaporation of fruit moisture and retain the fresh flavor of the fruit. Spray waxing nozzles are widely used in coloring for apples, citrus, pears and other fruits.
