OS-3200
Hot Quenching Machine

A hot quenching (blanching) machine is an industrial system designed to loosen the natural skins of nuts, primarily Almond, and also Peanut, Pistachio, and in some cases Hazelnut. In this process, raw nuts are immersed in hot water—typically 85–100 °C—for a short, controlled period. The heat softens the natural bonds between the skin and the kernel while the skin absorbs moisture and expands, allowing it to separate easily without damaging the nut. This method is widely used for almond peeling to produce clean white kernels for confectionery and bakery applications, while also supporting skin loosening for other nuts in various food processing operations. Designed for continuous industrial production, the machine ensures consistent treatment, gentle handling, and reliable preparation of nuts for the peeling stage.

Frequently Asked Questions

The OS-3200 immerses raw nuts in hot water, typically 85 to 100 °C, for a short, controlled period. This softens the bond between skin and kernel, so the skin can separate without damaging the nut. Its listed capacity is 200 kg/h, designed for continuous industrial production.

It is used mainly for almonds, and also for peanuts, pistachios and, in some cases, hazelnuts. Almond treatment helps produce clean white kernels for confectionery and bakery use. Suitability is confirmed for the intended application.

It prepares nuts for the peeling stage, so it is positioned ahead of the peeling operation in a line. The exact layout, including the feeding and discharge arrangement, is defined during project evaluation.

Please share the nut type, the required hourly output, the peeling method that follows, and the space and utilities available at your site. This allows the configuration to be assessed for your process.
