The value created by casings in small intestine processing has always been significant, as their value determines the overall economic benefits for producers. Therefore, we have conducted in-depth research on this technology and developed a method to extract more casings. Before scraping the casings, the small intestines are first treated with raw materials to increase their flexibility and reduce brittleness, ensuring they are less likely to break during the scraping process. This maximizes the value of using small intestines for casings. Action shapes the future, and details determine success or failure! The prices of small intestines vary by region, leading to different profit margins. Based on current average market prices for small intestines:

• Purchasing cost: ¥20 per small intestine.
• Using the researched casing technology: On average, 5 to 5.5 small intestines produce 100 meters of standard casings.
• Casing selling price: ¥1.50–1.60 per meter, totaling approximately ¥30 for 100 meters.
• Heparin sodium extraction cost: ¥0.50 per small intestine.
• Extraction ratio: 700 small intestines yield 1 kg of crude heparin sodium, with raw material costs of ¥350.
• Heparin sodium selling price: ¥8,500–11,000 per kg.
  
• Economic benefits analysis:
  
• The revenue from casings can cover the cost of purchasing small intestines and processing fees.
• Heparin sodium becomes pure profit.
• Daily processing of 30 small intestines can yield over 15 kg of heparin sodium annually, generating approximately ¥120,000 in annual profit from heparin sodium alone.
• If small intestines are purchased at around ¥20 each, casings can additionally generate profits, with total economic benefits reaching approximately ¥200,000 annually!
  
• Current market sales situation:
  
• Casings: Guaranteed sales price of ¥150–160 per 100 meters.
• Heparin sodium: ¥8,500–11,000 per kg.
  
• Based on recent domestic pig slaughter data, the supply-demand gap for casings and heparin is expected to widen further, with reduced export volumes and a rapid global price increase anticipated.
