Palm fruit sterilization system

Abstract

The invention relates to a palm fruit sterilization system. The palm fruit sterilization system comprises a fresh fruit bunch ramp, a fresh fruit scraper conveyor, fresh fruit temporary storage feeding devices, palm fruit sterilizers, cooked fruit hoppers and a cooked fruit scraper conveyor. An outlet of the fresh fruit bunch ramp is connected with an inlet of the fresh fruit scraper conveyor, an outlet of the fresh fruit scraper conveyor is connected with inlets of the fresh fruit temporary storage feeding devices, outlets of the fresh fruit temporary storage feeding devices are connected with feeding ports of the palm fruit sterilizers, and discharging ports of the palm fruit sterilizers are connected with inlets of cooked fruit hoppers. Each palm fruit sterilizer comprises a horizontal round barrel, wherein a feeding door is arranged on the upper portion of the head end of the barrel, a discharging door is arranged on the lower portion of the head end of the barrel, a driving shaft and a driving chain wheel are arranged at the head end in an inner cavity of the barrel, a driven shaft and a driven chain wheel are arranged at the tail end, a chain is wound around the driving chain wheel and the driven chain wheel and evenly provided with sterilizer scrapers, and sieve plates are arranged below the upper layer sterilizer scrapers and the lower layer sterilizer scrapers respectively. The sterilization system is small in investment, high in production efficiency and equipment use ratio and capable of cooking a shallow material layer at high pressure.

Description

technical field [0001] The invention relates to palm fruit oil production equipment, in particular to a palm fruit sterilization system, which belongs to the technical field of fruit processing machinery. Background technique [0002] After the fresh palm fruit is picked, it needs to be sterilized within 24 hours, otherwise the lipolytic enzyme in the fruit will quickly decompose the oil in it and turn it into glycerol and fatty acid, causing its economic value to drop sharply. [0003] There are two types of palm fresh fruit sterilization systems in the prior art. The first type uses tunnel type (horizontal) sterilization tanks. The sterilization system is composed of multiple sterilization tanks and supporting equipment, mainly including sterilization tanks, fruit Cage trains, loading platforms, winches, reversing piles, track bridges, cage dumpers, scraper conveyors, chain bucket elevators and other equipment, and are equipped with related track systems. Its working proc...

AI Technical Summary

Problems solved by technology

[0005] The first kind of sterilization system has the following disadvantages: 1. The system is complicated, the investment in equipment is large, the production efficiency is low, and it takes up a lot of space

2 High energy consumption, the total volume of the sterilization tank is 160 cubic meters, the volume of fresh fruit bunches is only 80 cubic meters, the volume utilization rate is 50%, the saturated steam in the cavity is 80 cubic meters in total, and the mass is 175kg, which is directly discharged. Contains grease, causing environmental pollution, low utilization rate of high pressure space

3. The safety is not good, the equipment is in a high temperature state, and it is necessary to manually pass through the steel cable attached to the sterilization tank, and the transition of the fruit cage train needs to be completed manually, which is labor-intensive

[0006] The second type of sterilization system uses a vertical sterilization tank, which effectively simplifies the process and equipment, but there are too many accumulations of palm fruit bunches, poor steam fluidity in the center, and poor cooking effect, resulting in uneven output quality

Moreover, after the ripening of fruit bunches, the strength decreases, and the excessive accumulation makes the bottom pressure of the stockpile high, and the ripened palm fruit is pressed to produce oil, forming a mixed solution of oil, water, and pectin. The oil precipitated in advance is easy to contaminate. degrade the quality of the oil
