Embodiment 1

[0066] 1. A series of tannin extract raw material ultrafine pulverization preparation and its use in series tannin extract product combination, coupled preparation process and method, characterized in that it includes the following steps:

[0067] The first step is the selection of raw materials for extract production: oak shells, larch, casuarina, oil orange, black wattle, myrica tomentosa, red root, oak, and bark of acacia.

[0068] The second step is the selection of tannin extract varieties and their forms: powdered oak tannin extract, powdered larch tannin extract, powdered casuarina tannin extract, powdered citrus tannin extract, powdered black wattle extract, Powdered bayberry extract, powdered red root extract, powdered oak tree extract, powdered acacia extract.

[0069]In the third step, the raw materials of oak bowl shell, larch, casuarina, oil orange, black wattle, myrica tomentosa, red root, oak, and acacia bark and their ultrafine powder preparation: the collected...

Embodiment 2

[0081] Weigh 500kg of 50-250 mesh rubber bowl shell ultrafine powder and place it in a 3000-liter glass-lined or stainless steel dynamic extraction tank with stirring and condenser. The extraction process adopts a low-temperature dual-dynamic three-tank three-step countercurrent extraction process or Flat type continuous extraction extraction process.

Abstract

The invention relates to a series tannin extract raw material ultra-fine crushing preparation as well as a combined and coupled preparation process and method for series tannin extract products. Prepared ultra-fine powder materials of valonia tannin extracts, larches, coast oaks, emblic leaf flowers, black wattles, myrica esculenta, red roots, live oaks and acacia mangium barks are respectively carried out by combined and coupled process and equipment processing of double-dynamic digestion or transition type continuous digestion, spiral sedimentation centrifuging separation (horizontal spiral unloading centrifuging separation), foam separation, sedimentation separation, plate frame filter pressing and the like, so as to correspondingly solve the problem that filtration, sol, micro-fine fiber grains, insoluble substances, non-tannin and the like in a producing and processing process of tannin extract raw materials are high. Therefore, the tannin extract products of industrial-grade valonia tannin extracts, larch tannin extracts, coast oak tannin extracts, emblic leaf flower tannin extracts, black wattle tannin extracts, myrica esculenta tannin extracts, red root tannin extracts, live oak tannin extracts and acacia mangium tannin extracts, which meet the industrial standard, are prepared.

Description

Technical field: [0001] The invention relates to the preparation of superfine powder raw materials of oak shell, larch, casuarina, oil orange, black wattle, myrica tomentosa, red root, live oak, and acacia bark and its use in rubber extract, Larch extract, Casuarina extract, Citrus extract, Black wattle extract, Myrica tomentosa extract, Red root extract, Oak tree extract, and Acacia extract method. The technology belongs to the technical field of plant crushing, extraction and separation of chemical engineering, and tannin extract processing industry. Background technique: [0002] The invention relates to the preparation of superfine powdered bark of oak bowl shell, larch, casuarina, oil orange, black wattle, myrica tomentosa, red root, live oak, and acacia bark and its application to oak bowl extract, Process and method for preparing larch extract, casuarina extract, oil orange extract, black wattle extract, bayberry extract, red root extract, oak tree extract, and acac...
