Liquid nitrogen fresh-keeping filling production line for camellia oleifera seed oil

Abstract

The invention discloses a liquid nitrogen fresh-keeping filling production line for camellia oleifera seed oil. The liquid nitrogen fresh-keeping filling production line comprises a conveying frame, acamellia oleifera seed oil filling machine, a filling device, a capping machine, a working platform and a box sealing machine; and the filling device comprises an automatic controller, an infrared optical sensor, a time-delay relay, an electronic flowmeter, an electronic filling gun and a liquid nitrogen tank. By quantificationally filling food-grade liquid nitrogen into oil bottles through the filling device, the oxidation effect of air on the oleifera seed oil can be isolated by the food-grade liquid nitrogen, under the condition that no preservative and no synthetic antioxidant is added, the inherent mouthfeel, taste and nutritive value of the oleifera seed oil are effectively preserved, in addition, the conveying speed of the oil bottles and the filling amount of the liquid nitrogen can be automatically adjusted by the filling device on the filling production line, or when the filling device breaks down, the filling production line is stopped in time for adjusting so as to guarantee the filling efficiency of the food-grade liquid nitrogen, thus the purpose of quick packaging for fresh keeping of the oleifera seed oil in the oil bottles is achieved, production is automaticallycontrolled under the safety guarantee, and the production efficiency is improved advantageously.

Description

technical field [0001] The invention relates to an edible oil production system, in particular to a liquid nitrogen fresh-keeping filling production line for camellia oleifera seed oil. Background technique [0002] Camellia oil, commonly known as camellia oil, also known as camellia oil and camellia seed oil, is a pure natural high-grade edible vegetable oil extracted from the mature seeds of common camellia oleifera (Camellia oleifera Abel) in the family Theaceae, with golden or light yellow color and pure quality , clear and transparent, fragrant smell, pure taste. As edible oil, camellia oil has a shelf life that varies according to the way it is stored. The common way of deterioration is camellia oil rancidity. The main reason for camellia oil rancidity is that it contacts with oxygen in the air, which oxidizes the unsaturated fatty acids in the oil. Tea oil loses its edible value. In order to prolong the shelf life of tea oil, the conventional method is to add various...

Problems solved by technology

[0003] To sum up, it is generally necessary to add antioxidants or use gas nitrogen to preserve freshness of edible packaged oil. The former method cannot achieve the safe and natural freshness preservation method that consumers are pursuing now. The latter is extremely volatile due to gas nitrogen, which is difficult to obtain in actual production. It is often difficult to guarantee the effect during operation
