Description

Technical Field

[0001] The present invention belongs to the technical field of automatic filling of edible oil, and specifically relates to an automatic filling device for edible oil under atmospheric negative pressure and its control method. Background Art

[0002] Edible oil, also known as "cooking oil", refers to animal or vegetable oils used in the process of making food. It is liquid at room temperature. Due to reasons such as raw material sources, processing techniques, and quality, common edible oils are mostly vegetable oils, including rapeseed oil, peanut oil, hemp oil, corn oil, olive oil, camellia oil, palm oil, sunflower seed oil, soybean oil, sesame oil, linseed oil (flaxseed oil), grape seed oil, walnut oil, peony seed oil, etc. An automatic filling device for edible oil under atmospheric negative pressure is a very practical industrial device, mainly used for filling liquid products such as edible oil, beverages, and medicines. The automatic filling device for edible oil under atmospheric negative pressure forms a negative pressure in the bottle by pumping vacuum, and then uses atmospheric pressure to transport the liquid from the storage tank to the bottle. In daily life, edible oil is usually filled in barrels. In the production process of edible oil, the raw materials are extracted to obtain edible oil, and then the edible oil is filled into barrels by an automatic filling device for edible oil under atmospheric negative pressure, and after sealing treatment, it is packed and transported for sale.

[0003] The existing automatic filling device for edible oil under atmospheric negative pressure and its control method have certain drawbacks when in use. The existing automatic filling device for edible oil under atmospheric negative pressure and its control method usually use different filling bottles for filling and storage, but most of them use plastic bottles for filling. When vacuum negative pressure filling is carried out on plastic bottles, due to the relatively soft material and thin wall thickness of plastic bottles, they are prone to deformation or even rupture under a large internal and external pressure difference. As a result, the automatic filling device for edible oil under atmospheric negative pressure needs to be stopped and manual replacement of new filling bottles is required by staff, which reduces the filling efficiency of the automatic filling device for edible oil under atmospheric negative pressure and causes economic losses to people, and cannot meet people's needs.
