Problems solved by technology
However, the peeling method of local enterprises for lotus seeds stays at the stage of manual operation with a simple mechanical peeling device. This peeling method is labor-intensive, processing efficiency is low, and labor costs are high. It is difficult to ensure hygiene requirements and difficult Realize industrialized production, and it is easy to damage the lotus seed meat. At the same time, the secondary cleaning and heating and ripening still need to be carried out after peeling, which greatly increases the production energy consumption of lotus seed products

Embodiment Construction
[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] As shown in the figure: a method for peeling fresh lotus with temperature and pressure variation described in the present embodiment includes the following steps: feeding fresh lotus, punching lotus skin, conveying lotus seeds, increasing temperature and pressure, releasing pressure and peeling, The skin and flesh are sieved and collected; it can be seen that the particle size of the fresh lotus seeds with the processing quality requirements is 15-20mm, and the fresh lotus seeds are placed in the carbon steel to make the feeding funnel container 1. The upper rectangular box volume size of the feeding funnel container 1 is 0.5-1m3 , used for the storage of fresh lotus seeds, the central contraction section is 45º-60º conical design, used to reduce the flow rate of lotus seeds, the bottom feeding pipe diameter is 20-40mm, and the electromagn...

A method for peeling fresh lotus with temperature and pressure change mainly solves the technical problems of low peeling efficiency of fresh lotus, poor peeling effect and damage to lotus flesh under the prior art. The main points of its technical scheme are: including fresh lotus feeding, lotus skin pretreatment (punching), lotus seed transportation, temperature increase and pressure, pressure relief peeling, skin and flesh screening, and lotus flesh collection. The sealing device is carried out in the form of electric heating, and electromagnetic sensor control elements are used for pressure relief and peeling; the production method of "increasing temperature, pressurizing and instantaneous pressure relief to realize the peeling process of fresh lotus" can effectively ensure the separation of the skin and flesh of the final fresh lotus; It saves labor resources and reduces the damage of lotus flesh to the greatest extent. The whole system is integrated to realize mechanized and automated production, effectively improve the quality of lotus flesh, reduce production costs, and truly realize the peeling processing of fresh lotus with high efficiency and low loss.
Description
technical field [0001] The invention relates to a peeling process for fresh lotus, in particular to a method for peeling fresh lotus with temperature and pressure variation. Background technique [0002] Hunan Xiangtan is also known as "Liancheng" because of its rich production of Xianglian. The production of Xianglian accounts for 63.4% of the country's total. The lotus seed manufacturing industry continues to expand and the demand continues to increase, which puts forward higher requirements for the processing technology of lotus seeds. Peeling is the processing technology of lotus seeds. an important process. However, the peeling method of lotus seeds by local enterprises remains at the stage of manual operation with simple mechanical peeling devices. Adopting this peeling method is labor-intensive, processing efficiency is low, labor costs are high, and it is difficult to meet hygienic requirements. The industrialized production is realized, and the lotus seed flesh is ...
