Perforating machine for refrigerated berries and production process of dried berries

Abstract

The invention discloses a perforating machine for refrigerated berries and a production process of dried berries. The perforating machine comprises a belt conveyor and is characterized in that a base plate is provided with considerable arc bumps, a pore plate is in fixed connection with a slide bar and is perforated with considerable penetrated small holes, a nail plate is arranged above the pore plate and slidably sleeved and arranged on the slide bar through a sliding sleeve, the nail plate is provided with considerable barbed nails capable of passing through the small holes, an upper support is in fixed connection with the slide bar, and the nail plate is connected with a power-driven eccentric wheel through a connecting rod. The perforating machine provided by the invention has the advantages of a simple structure, uniform perforation, applicability to berries with different diameters, easy realization of mechanized operation, a fast freeze-drying and dehydration speed and capacity of obtaining an intact fruit shape; and compared with traditional manual perforation, the perforating machine provided by the invention enables labor force to be substantially saved.

Description

technical field [0001] The invention relates to a fruit processing method and equipment thereof, in particular to a frozen berry punching machine and a production process of dried berries. Background technique [0002] Berries generally have a short shelf life due to texture and other reasons and are more suitable for fresh eating. If they can be made into dried fruits, they are more conducive to the public's consumption at any time. However, for some special berries such as blueberries, it is not suitable to adopt the air-drying method to obtain dried fruit. They can be dehydrated by sublimation under freezing conditions. The above-mentioned problems can be solved by piercing the berries in the frozen state. [0003] For example, the automatic punching machine for fresh cucumbers (ZL201020516496.5) uses an electric device to automatically punch holes, and uses a crank structure that can rotate 360° to remove melons; while the embryo automatic punching machine (ZL2010200158...

Problems solved by technology

However, for some special berries such as blueberries, it is not suitable to adopt the air-drying method to obtain dried fruit. They can be dehydrated by sublimation under freezing conditions. The above problems can be solved by piercing the berries in the frozen state

[0003] For example, the automatic punching machine for fresh cucumbers (ZL201020516496.5) uses an electric device to automatically punch holes, and uses a crank structure that can rotate 360° to remove melons; while the embryo automatic punching machine (ZL201020015807.X) uses cylinder pistons to drive Puncture needles are used to puncture the surface of the tire, and the bottom is conveyed by rollers, but none of them are suitable for small berry puncture and automatic shedding. Therefore, it is necessary to provide a puncture equipment suitable for small berry puncture and automatic shedding to meet the needs of production.
