Description
Technical Field
The invention relates to the technical field of food processing, in particular to a method and a device for recycling reclaimed water in water for processing concentrated fruits and vegetables.
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 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. The concentrated fruit and vegetable processing industry generally prepares the product by pre-processing (cleaning, selecting, crushing, preheating, pulping and the like of raw materials), vacuum concentration (in a certain vacuum environment, the process of evaporating water out of materials is vacuum concentration, also called evaporation concentration), sterilization, cooling and filling. The purpose is to reduce water in the concentrated fruit and vegetable products and reserve the nutrient components in the concentrated fruit and vegetable products as much as possible. So as to achieve the purposes of long-term storage, package and transportation cost reduction and convenient carrying and use by consumers.
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 first reason is that the raw material flushing and discharging water is recycled only after being subjected to coarse filtration and fine filtration. It is known that the tomato (for example, a certain amount of soil and faraway soil are mixed in the raw material of mechanically harvested tomatoes) has more silt and suspended matters in the water, and the silt and suspended matters in the water cannot be filtered out only by a filtering 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.
