Embodiment 1

[0034] A compressed storage process for expanded tobacco stem products, the process steps are as follows:

[0035] A. Moisture control, using a drying cylinder to dry the expanded tobacco stem products (expanded stem particles, expanded stem strips or expanded stem shreds) to a moisture content of 13wt%;

[0036] B. Increase temperature, use 80°C hot air to heat the expanded tobacco stem product to 55-75°C;

[0037] C. Press the stem, compress the expanded tobacco stem product to 15% to 25% of the original volume, and make a rectangular block with a thickness of 100mm to 200mm, a length of 1100mm, and a width of 700mm

[0038] D. Packing and storing, after packing the compressed stalks into boxes with the same quantity per box, store them under ventilated conditions with a temperature of ≤38°C and a humidity of ≤70% through logistics;

[0039] E. Loose recovery, the stored compressed stalks will be used in subsequent processes after being loosened and recovered in vacuum.

Embodiment 2

[0041] The expanded stalks with a moisture content of 26wt% are dried by HT+drum to a moisture content of 13.5wt%, heated to 48°C by hot air, and compressed to 25% of the original volume by a KY161 pre-pressing machine to produce a thickness of 175mm. , 1100mm in length and 700mm in width; each 4 pieces should be packed into a corrugated box; stored for 1 year under ventilated conditions with a temperature of ≤38°C and a humidity of ≤70%; when in use, loosen and recover by heating with 915MHz microwave after unpacking Volume is enough.

Embodiment 3

[0043] The expanded stalk granules with a moisture content of 29wt% are dried to a moisture content of 15wt% through a Venturi tube + expansion tower, heated to 90°C by 2450MHz microwave, and compressed to 80% of the original volume by a single hydraulic pre-compressor. Make stalks with a thickness of 50mm, a length of 1100mm, and a width of 700mm; put 14 pieces into a corrugated box; store for 2 years under ventilated conditions with a temperature of ≤38°C and a humidity of ≤70%; when used, pass through a vacuum after unpacking The way of regaining moisture is to loosen and restore the volume.

Abstract

The invention provides a compression storage process for expanded tobacco stem products and belongs to the technical field of cigarette filling materials. The compression storage process includes the steps of A, moisture control by drying the expanded tobacco stem products until their moisture contents reach 10-15wt%; B, temperature rise by heating the expanded tobacco stem products to the temperature of 40-90 DEG C; C, stem compression by compressing the expanded tobacco stem products until their volumes become 10-80% of the original volume to obtain compressed stem cakes; D, packing for storage by packing the compressed stem cakes in boxes according to the equal quality and then storing; E, recovery of looseness by recovering volumes of the stored compressed stem cakes for the subsequent process. According to the compression storage process, conveying cost of the expanded tobacco stem products is reduced effectively, storage space is saved, storage time is prolonged, peculiar smell and offensive odor components of the expanded tobacco stem products are reduced, and especially the charring smell is removed; the compression storage process is carried out based on the existing proven tobacco industrial equipment, is simple and practical, and can be applied in a wide scope of tobacco enterprises.

Description

technical field [0001] The invention relates to a processing method for expanded tobacco stem products, in particular to a compression storage process for expanded tobacco stem products, and belongs to the technical field of tobacco cigarette fillers. technical background [0002] Tobacco is a plant of the genus Nicotiana in the family Solanaceae. The tobacco stem is the thick and hard vein of the tobacco leaf, accounting for about 25% to 30% of the leaf weight. It is a by-product of the tobacco industry. In order to make full use of tobacco stem resources, reduce the amount of tar released from cigarettes and reduce the consumption of cigarette raw materials, tobacco stems are usually made into expanded stem particles, expanded stem strips, expanded stem shreds and other products and added to cigarettes for application. And along with the extensive use of various forms of expanded tobacco stem products in the tobacco industry, its various drawbacks are also constantly revea...
