AI Technical Summary
Technical Problem
Traditional raw hide tanning methods consume large amounts of water and chemicals, leading to environmental pollution and energy consumption, and require extensive purification treatment, resulting in high costs.
Method used
The process involves using a heat-insulated treatment chamber to spray water and chemicals in droplet or aerosol form for washing, deliming, softening, pickling, tanning, and cross-linking steps. This avoids immersion in a treatment bath, controls temperature, humidity, and water volume, and reduces the amount of water and chemicals used.
Benefits of technology
Significantly reduces water and chemical use, lowers energy consumption, reduces water purification and air pollution, and improves the sustainability and economic benefits of raw hide processing.

Abstract
A method for processing hides includes the following steps: washing the raw hides to be processed with water; deliming the raw hides with a suitable deliming agent to remove residual lime; softening the raw hides with a suitable softening agent to remove keratin degradation products, hair, and epidermal residues; rewashing the raw hides with water; pickling the raw hides with a suitable pickling agent to lower the pH value; tanning the raw hides with a suitable tanning agent to prevent microbial attack; and crosslinking the raw hides with a suitable crosslinking agent to permanently fix the tanning agent to the raw hides. Each stage of washing, deliming, softening, rewashing, pickling, tanning, and crosslinking is carried out in a processing chamber that is thermally insulated from the external environment, wherein the temperature, humidity, and water volume within the chamber are continuously monitored.
