Method for recycling water in laver processing

Abstract

The invention discloses a method for recycling water in laver processing. The method includes a process of recycling the water produced by a laver processing machine, and a process of adopting the recycled water as the raw material to produce beverage. The process of cycling the water produced by the laver processing machine comprises the following steps: draining the water into a flow splitting tank by a draining pipe of the laver processing machine; automatically adjusting a switch valve to be switched on by virtue of the flow in a water outlet when the water in the flow splitting tank is accumulated to be higher than the water outlet; pumping the water to a material inlet of the laver processing machine by a water pump; automatically adjusting the switch valve to be switched off once the water circulating volume reaches a set volume; draining the water from another water outlet; filtering the water, and transferring the water into an ultrahigh-temperature instant sterilizer to sterilize; and then storing the water into a storage tank and sealing after the sterilizing. The process of adopting the recycled water as the raw material to produce beverage comprises the following steps: taking the sterilized circulating water as the raw material; and mixing the sterilized circulating water with auxiliary materials; filtering by a beverage filter; transferring water into the ultrahigh-temperature instant sterilizer to sterilize; and then filling by a filling machine after sterilizing. The laver residues obtained by filtering can be used as feeds or vegetable fertilizers.

Description

Technical field: [0001] The invention relates to the technical field of water treatment, in particular to a method for dehydration and recycling of a laver processing machine in the laver processing process, including the dehydration and recycling of the laver processing machine and a method for producing beverages using circulating water as a raw material. Background technique: [0002] Porphyra is a kind of economical algae cultured artificially. It has high nutritional value and is a kind of green food. By 2009, my country had more than 500 sets of fully automatic processing units for dry laver, with an annual processing capacity of about 6 billion sheets of dried laver. The currently used processing models mainly include NH-6 type (double-layer drying), NH-8 type, NS-6 type (single-layer drying), NS-6 extended type and a small number of other types of units, of which imported units account for More than 80%. In the traditional laver processing process, the water remove...

Problems solved by technology

This high cost is also accompanied by environmental pollution. A large amount of organic wastewater and waste residues discharged by the seaweed processing industry are directly discharged into the river and sea, which has caused the threat of eutrophication to the river and sea and seriously polluted the environment.

Therefore, the discharge of the production water not only costs a high production cost, but also pays a heavy price for environmental pollution.
