Description

Cooling system for storage and transportation Every Other Day To Maintain The Freshness of Milk

The present invention relates to a cooling device for storage and transport for every other day for maintaining the freshness of crude oil (milk before milking and processing is referred to as crude oil). It relates to a cooling device for storage and transport for every other day to maintain the freshness of crude oil, which consists of a cold chain that covers all processes up to transport.

The crude oil each milked from the cows is collected in one oil collecting tank, and the crude oil collected in the oil collecting tank is cooled by a cooler provided integrally in the oil collecting tank, so that the collected crude oil is transferred from the oil collecting tank to the oil collecting tank lorry. It allows the freshness to be maintained so that there is no deterioration such as bacterial propagation until it is transferred and transported to the milk processing plant.

In general, since milk milked from cows maintains a temperature of 36 ° C, there is a very high risk of deterioration of the crude oil. For this reason, in order to maintain freshness, it is customary to store or ship the crude oil collected and stored in the oil collecting tank by cooling it to 4°C from the crude oil cooler. Such a crude oil cooler has been published in the following patent documents.

First, Patent Document 1 discloses that 'a crude oil cooler includes a cooling water storage tank in which cooling water is stored; a main cooling unit connected to the cooling water storage tank and a first circulation line, the cooling water circulating through the first circulation line and the milking oil are heat-exchanged and cooled to 2 to 6°C; Connected to the cooling water storage tank and the second circulation line, the cooling water circulating through the second circulation line is heat-exchanged with crude oil before being introduced into the main cooling unit to provide a pre-cooling unit for pre-cooling to 8 to 12 ° C. By this, it is possible to prevent the quality deterioration of crude oil by pre-cooling the milked crude oil to 8 to 12 ° C before cooling it to 2 to 6 ° C, which is the storage temperature, and also to provide safe crude oil by cooling the crude oil using cold cooling water. It is to provide a crude oil cooler that can

Patent Document 2 states, 'The outer periphery of the stainless cooling plate is welded to the outer surface of the bottom plate of the stainless cooling tube to form a sealed state, and the welding point attached to the bottom plate is formed in several places at regular intervals on the middle plate surface of the cooling plate at regular intervals. Crude oil cooler, characterized in that between the cooling plate and the bottom plate, the cooling gas distribution void through which the cooling gas can branch and flow is formed into a thin space,

Patent Document 3 relates to 'a tank lorry for collecting milk for separate oil collection, dividing the tank for an oil collecting vehicle into two or three parts as needed, and a transfer pipe for transferring from a transfer pump installed inside the oil collection chamber to the tank. Each valve is installed to enable separate collection of milk by grade, and one milk collecting vehicle can collect various grades of milk to reduce vehicle operating costs. It is possible to improve the quality of milk by preventing it from being mixed with milk from being deteriorated.'

However, the cooling of crude oil of the prior art disclosed in the above patent documents is performed only to prevent deterioration of crude oil in the initial oil collection state, and continuous cooling of the crude oil is not made until it is transported to a crude oil processing plant, so there is a risk of lowering the freshness of the crude oil. In addition, there was a concern about the quality of crude oil due to the mixing of hot crude oil collected later in the crude oil cooled first when collecting crude oil every other day.

Therefore, there is an urgent need for the development of a crude oil cooling system to maintain a stable cooling state so that there is no deterioration in quality due to deterioration of crude oil during transportation from milk collection of milk milked from a cow cow to a milk factory.
