Problems solved by technology

The existing process controls the color of bamboo slices mainly through chemical agents (hydrogen peroxide, sodium pyrophosphate and other chemical agents) to achieve the required color after cooking, and the processed bamboo slices contain a large amount of heavy metals, formaldehyde, benzene, volatile organic compounds and other harmful substances. The substances seriously exceed the standard, which is detrimental to human health, and the boiled potion has great damage to the natural environment and does not meet environmental protection requirements

Embodiment 1

[0036] A kind of bamboo chip toning technology based on temperature-controlled drying carbonization, comprises the following steps:

[0037] (1) Under the condition of an ambient temperature of 5 °C, a batch of light yellow bamboo chip blanks (such as figure 1shown) into a heating device, start the heating device to quickly heat up to 120°C, first preheat the bamboo blank, and at the same time keep turning the bamboo blank to make it evenly heated, after the bamboo blank is heated, the contained The water evaporates and escapes into the inner cavity of the heating device. After 1 hour of preheating, the humidity sensor detects that the humidity of the gas inside the heating device is 60%;

[0038] (2) Transfer the measured humidity parameters to the controller of the heating device, and use the three-dimensional working model of "humidity-heating system-color selection" preset in the controller to determine the heating of the heating device in the batch of bamboo blanks. syst...

Embodiment 2

[0044] A kind of bamboo chip toning technology based on temperature-controlled drying carbonization, comprises the following steps:

[0045] (1) Under the condition of an ambient temperature of 5 °C, a batch of light yellow bamboo chip blanks (such as figure 1 shown) into a heating device, start the heating device to quickly heat up to 120°C, preheat the bamboo blanks first, and at the same time keep turning the bamboo blanks to make them evenly heated, after the bamboo blanks are heated, the moisture contained in them The evaporation escapes into the inner cavity of the heating device. After 1 hour of preheating, the humidity sensor detects that the humidity of the gas inside the heating device is 60%;

[0046] (2) Transfer the measured humidity parameters to the controller of the heating device, and use the three-dimensional working model of "humidity-heating system-color selection" preset in the controller to determine the heating of the heating device in the batch of bambo...

Embodiment 3

[0052] like Figure 4 to Figure 11 Shown, a kind of bamboo chip toning device comprises the cylinder 2 that is installed on the frame 1 and the driving assembly 3 that drives the cylinder 2 to rotate, and the circumferential side wall of the cylinder 2 is provided with feed inlet 22 and with feed inlet 22 matched dodge door 21, the dodge door 21 is hinged at the feeding port 22 of the drum 2 and is provided with a lock, which can be opened and closed as required. The inner chamber of the drum 2 is provided with a heating assembly 4, a temperature sensor 5 and a humidity sensor 6. The bamboo chip toning device also includes a peripheral controller (not shown in the figure), the heating component 4, the temperature sensor 5 and the humidity sensor 6 are all connected to the controller, and the heating component 4 is fixed in a non-contact bamboo chip At the axis of rotation of the drum 2, it provides heat at the center of the drum 2, achieving stability and ease of operation of ...

Abstract

The invention discloses a bamboo sheet coloring process and device based on temperature-controlled drying carbonization. The coloring process comprises the steps of preheating for detecting humidity, selecting a heating system, heating for carbonizing, and cooling, thereby obtaining a finished product. The bamboo sheet coloring device comprises a roller on a rack, a driving component for driving the roller to rotate, and an external controller, wherein the side wall of the roller is provided with a feeding hole and a movable door matched with the feeding hole, an inner cavity of the roller is internally provided with a heating component, a temperature sensor and a humidity sensor which are all connected with the controller, and the heating component is fixed on the rotating axis of the roller in a manner of not containing a bamboo sheet. The coloring process and device have the advantages of energy conservation, environment protection, uniformity in coloring, easiness in implementation, full-automatic intelligent control, labor saving and the like.

Description

technical field [0001] The invention relates to the technical field of bamboo processing, in particular to a temperature-controlled drying and carbonization-based bamboo chip toning process and a bamboo chip toning device. Background technique [0002] Summer mat is an important article for enjoying the cool air and evacuating the heat that is generally used in summer. Present bamboo sheets for summer mat etc. need to change colors according to people's aesthetic requirements after being processed into required small bamboo sheets by bamboo. The existing process controls the color of bamboo slices mainly through chemical agents (hydrogen peroxide, sodium pyrophosphate and other chemical agents) to achieve the required color after cooking, and the processed bamboo slices contain a large amount of heavy metals, formaldehyde, benzene, volatile organic compounds and other harmful substances. The substances seriously exceed the standard, which is detrimental to human health, and ...
