Machine for peeling bulb and tuber products. This machine treats the product in preparation for the removal of the peel. In the steam peeler the products are stripped of their peel using steam under a certain pressure. This pressure causes the water to boil just under the skin and the shell is quickly dislodged from the product by reducing the steam pressure. Because the bulb and tubers are not completely free of sand and soil, there is a lot of wear on the stuffing box packing which seals the hollow shaft to the boiler in which the product is treated. In addition, due to the use of an often unsuitable gasket, there is a sleeve shaft at the level of the gasket. Injecting the shaft or replacing is an expensive solution. Due to the leakage of the steam along the packing chamber that blows directly onto the bearing seal and thus ends up in the bearing, the service life of the bearing is very low. There is also a lot of steam leakage.
The Sellon solution
Installing “rotary live-loading” disc springs in combination with Chesterton stuffing box packing type 1730, This spring technique creates a constant pressure on the gland packing so that sand and soil no longer have a chance to penetrate between the gasket and the shaft. By using the new gasket, shaft wear is prevented at the same time. The steam leakage has also stopped. Costs that came back annually such as spraying sleeves, replace the bearing, and the steam leakage is a thing of the past. Preventive now only the gasket is replaced annually.
Application has been running for 9 years without high costs.
