Embodiment 1

[0022] A method of utilizing geothermal water to preserve freshness of sweet potatoes, the specific steps are as follows:

[0023] 1) Fresh-keeping warehouse construction:

[0024] The construction of the storehouse adopts a brick concrete structure, and the wall of the fresh-keeping storehouse is 26 meters long, 15 meters wide, and 4 meters high. The storage capacity accounts for 70% of the total space; "Sweat", water droplets;

[0025] 2) After the storage body is completed, it will be equipped with automatic temperature control and humidity control devices:

[0026] 20 cm high around the wall, lined with 2-inch hot-dip galvanized pipes, and the pipe ends are connected to the water pump outlet pipe of the geothermal well. The geothermal well is 1200 meters deep, and the water temperature is 48°C; The sealing tape is used to seal to prevent the hot-dip galvanized pipe from leaking and flowing into the fresh-keeping warehouse; the automatic control switch is installed at the...

Abstract

The invention discloses a method of retaining the freshness of sweet potatoes by geothermal water. In the severe winter, the outside temperature is low; the temperature in a freshness retaining warehouse is reduced with the outside temperature; when the temperature in the freshness retaining warehouse is reduced to be lower than 9 DEG C, a temperature sensor of the freshness retaining warehouse is switched on by a temperature controller, and an automatic water supply switch supplies water; geothermal water with the temperature of 48 DEG C is conducted and dispersed into the sweet potato freshness retaining warehouse through a 2-inch hot-galvanized pipeline; when the temperature in the warehouse returns back to 14 DEG C, the temperature controller informs the water supply switch to stop supplying water so as to effectively control the sweet potato freshness retaining temperature within 9-14 DEG C all the time; therefore the problem of kiln burning caused by a large amount of breathing heat release after sweet potatoes are harvested and the problem that the sweet potatoes are infected with soft rot diseases and rotten in the kiln due to low temperature in the severe winter are solved. As the practical geothermal water is fed through the pipeline for sweet potato freshness retaining, the influence caused by winter low temperature in the sweet potato freshness retaining warehouse on large-scale sweet potato freshness retaining is avoided, and the aim of large-scale sweet potato freshness retaining is fulfilled.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for keeping sweet potatoes fresh using geothermal water. Background technique [0002] Sweet potato is a major agricultural product with rich nutrition, homology of medicine and food, and wide range of uses. Because of its high water content, high sugar content, and high starch content, it is easy to rot and deteriorate. Therefore, the preservation of sweet potatoes has not been properly and effectively solved, especially in winter, sweet potatoes are afraid of freezing, and the winter storage of sweet potatoes is a difficult problem, which directly affects the implementation of the two-potato development strategy in our city and the development of the rural economy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an easy-to-implement and feasible method for fresh-keeping sweet potatoes by using geother...
