Embodiment Construction

[0016] Below in conjunction with red jujube juice example the present invention is described in detail, but not limited thereto. The methods described in the examples are all conventional methods unless otherwise specified.

[0017] (1) Pre-coating: first use perlite, then diatomaceous earth, control the vacuum degree of 0.04Mpa, and pre-coat 4cm. After the pre-coating, a 15min repair cycle is carried out.

[0018] (2) Enter jujube juice, control vacuum degree 0.06Mpa.

[0019] (3) Adjust the feed rate to slow, feed once every 8s.

[0020] (4) When filtering, it is necessary to quantitatively add diatomite of the same specification as the pre-coating to the turbid liquid of the material, stir evenly, and filter; the diatomite and the solid matter in the material are intercepted by the pre-coating together and remain in the pre-coating. layer of diatomaceous earth.

[0021] (5) The filtrate is collected and subjected to ultrafiltration.

[0022] (6) After the filtration is...

Abstract

The invention belongs to the field of farm produce processing, in particular to a vacuum drum filter and an operating method thereof prior to the ultrafiltration of fruit / vegetable juice. The operating steps include: precoating, material feeding, cutting feed, filtrate collection and cleaning. Before the ultrafiltration of the fruit / vegetable juice, if the viscosity of the material is overhigh and impurities are excessive, the flux of ultrafiltration can be affected, and as a result, the whole continuous fruit / vegetable juice production process can be affected. After the fruit / vegetable juice is filtered by a vacuum drum, the viscosity of the fruit / vegetable juice is decreased, impurities are reduced, consequently, the flux of the ultrafiltration of the fruit / vegetable juice is increased, the flux decrease rate is decreased, and the energy consumption of production is reduced.

Description

Technical field: [0001] The invention belongs to the field of agricultural product processing, and relates to a vacuum drum filter and a working method thereof before fruit and vegetable juice ultrafiltration. Background technique: [0002] Drum vacuum filter is a continuous filtering equipment, which has the advantages of continuous filtering, washing, high degree of automation, small footprint, and strong adaptability to materials. Therefore, it is widely used in various fields that require solid-liquid separation, such as pharmaceuticals, fruit juices, and sewage treatment. [0003] Before ultrafiltration of fruit and vegetable juice, if the viscosity of the material is too high and there are too many impurities, it will affect the flux of ultrafiltration, thereby affecting the continuous production process of fruit and vegetable juice. After the fruit and vegetable juice is filtered by the vacuum drum, the viscosity of the fruit and vegetable juice is reduced, the impur...
