Description

Reclaimed water recycling device in concentrated fruit and vegetable processing water

Technical Field

The utility model relates to a concentrated fruit and vegetable processing technology field is a recycled water cyclic utilization device in concentrated fruit and vegetable processing water.

Background

In the concentrated fruit and vegetable processing industry, the evaporated water in the raw material processing, evaporating and concentrating process is called regenerated water, the raw material flushing and discharging water is the raw material flushing and discharging water of a material pool, and the raw material flow water is the raw material conveying water for conveying raw materials into a raw material flow groove. The first-grade water is fresh water (or clean water) used in the processing process of concentrated fruits and vegetables, and the cleanliness of the first-grade water is highest; the second-grade water is water which is reused after the first-grade water is used, and the cleanliness of the second-grade water is inferior to that of the first-grade water; the third-level water is water which is reused after the second-level water is used, and the cleanliness of the third-level water is inferior to that of the second-level water.

At present, in the new technology of 'three-stage repeated and recycling method of production water in tomato sauce factory' in the concentrated fruit and vegetable processing industry, the technology has the following defects and problems, and has not been widely popularized in nearly 8 years. The reason is that the raw material flushing and discharging water is recycled only by coarse filtration and fine filtration, and we know that the water of flushing and discharging (such as mechanically-harvested tomato raw materials mixed with a certain amount of soil and farrow) contains more silt and suspended matters, and the silt and suspended matters in the water cannot be filtered only by a filtration mode. The silt and suspended matter concentration after 1 day is unreasonably high when the silt and suspended matter are repeatedly recycled. The slurry water used for flushing and discharging raw materials does not meet the food processing requirements, and cannot be accepted by processing factories. The other reason is that the raw material flow water and the spray rinsing water are repeatedly recycled after coarse filtration and fine filtration, and the particle suspended matters in the water cannot be removed only by filtration. Suspension concentrations of approximately one hundred cycles (15 minutes per cycle) per day are not conceivable. The water is repeatedly recycled, and is not welcomed by the processing enterprises. The third reason is that the prior art only considers the problem of the repeated recycling of the three-level water in the aspects of the flushing, unloading, flowing and spraying and floating of the raw materials, but does not consider the problem of water consumption of all equipment on a production line and fully utilizes the regenerated water as a new water source to completely replace the existing water source.
