Embodiment 1

[0029] Complete machine is supported by frame 12.

[0030] The camphor leaf is manually fed to the feeding table 1, and is forced to be rolled by the biting roller 2 to be sent between the fixed cutter 3 and the rotary cutter 4, and is shredded by the rotary cutter 4.

[0031] The chopped materials naturally scatter into the closed space of the pretreatment area 13, and accumulate on the porous chain plate 7, and move to the distillation station along with the porous chain plate 7. Before entering the closed distillation station, the thickness of the material on the porous chain plate 7 is controlled to be 30 cm by the adjustable baffle 11 and the adjustable scraper 8 .

[0032] The steam zone 10 and the distillation zone 5 correspond to sections, and the temperature of each section is different and increases step by step. By automatically controlling the temperature of steam zone 10, 10-1 is 98°C, 10-2 is 108°C, 10-3 is 118°C, 10-4 is 128°C, 10-5 is 138°C, 10-6 is 148°C, 10 ...

Embodiment 2

[0034] Embodiment 2: Camphor leaves are manually fed to the feeding table 1, and are forced to be wound by the opposing roller 2 to be sent between the fixed cutter 3 and the rotary cutter 4, and are chopped by the rotary cutter 4.

[0035] The porous chain plate 7 is provided with a vertical adjustable scraper 8, and the distance between two adjacent adjustable scrapers 8 is consistent with the lateral dimension of the distillation area 5, which can not only prevent the material from slipping, but also better Realize the environmental sealing of the distillation station.

[0036] The chopped materials naturally scatter into the closed space of the pretreatment area 13, and accumulate on the porous chain plate 7, and move to the distillation station along with the porous chain plate 7. Before entering the closed distillation station, the thickness of the material on the porous chain plate 7 is controlled by the adjustable baffle plate 11 to 65cm.

[0037] The steam zone 10 an...

Abstract

The invention relates to a method for continuously distilling aromatic oil by subsectional temperature control. The method is characterized by comprising the following steps of: after cutting raw materials to crushed aggregates, falling to a mobile conveying device; and forming a close and independent distilling work station by different distilling area and corresponding steam areas; continuously passing through the crushed aggregates by all distilling work stations to complete distillation step by step. The method provided by the invention has the positive effects that the daily handling capacity is improved by continuous feeding, distillation and discharge. Through closed cutting, vapor-solid materials are more uniformly contacted, so that vapor collapse and short circuit are effectively avoided. The temperature is controlled by sub-sections and is gradually raised to the benefit of more adequate distillation-off of aromatic oil (conventional components) in raw materials; different azeotropes (coarse distilling materials) which are collected in sub-sections are overcome for the convenience of post-process. Higher temperature distillation is realized. Shallow distillation overcomes the deficiency that steam is hard to penetrate through material layer during distillation in a barrel, so that the thermal efficiency of distillation is improved.

Description

technical field [0001] The invention relates to a method for continuously distilling aromatic oil with segmental temperature control, in particular to a method for continuously distilling aromatic oil with segmental temperature control at a temperature higher than normal pressure water vapor after destroying the cuticle of branches and leaves. Background technique [0002] The traditional method for extracting aromatic oils is retort steam distillation. During distillation, the water in the bottom pot of the retort is heated to generate steam, and the azeotrope with a boiling point lower than 100°C in the whole branches and leaves is stripped, and the distillate is exported at the top of the retort, and the crude oil is obtained through condensation. The disadvantages of traditional crafts are: [0003] 1. With intermittent operation, only one batch of materials can be processed quantitatively (depending on the volume of the retort) at one time. After the materials have be...
