Food-grade Stainless Steel Filter Press (Tequila Filtration) Customer Case Study

I. Basic Customer Information

Customer Name: A Premium Tequila Distillery

Core Business: Specializing in the research and development, production, and sales of tequila, focusing on mid-to-high-end handcrafted tequila. The products adhere to Mexican tequila production standards, emphasizing the purity and flavor retention of the liquor. The distillery needs to obtain relevant food safety production certifications.

Customer Pain Points: During the filtration process after distillation and before bottling, it is necessary to effectively retain sediment (such as agave residue and small impurities generated during fermentation) and powder activated carbon used for decolorization and purification. At the same time, the equipment must meet food-grade standards, without the release of metal ions, and not alter the original flavor and quality of the tequila. The equipment volume should be suitable for small-batch production, and be easy to operate and maintain.

II. Core Customer Requirements

• Equipment Specifications: Volume of 60L, suitable for small-batch tequila filtration, meeting the filtration volume requirements of a single batch, while balancing efficiency and flexibility.
• Filtration Purpose: Specifically designed for tequila filtration, to efficiently retain sediment and powder activated carbon, ensuring the liquor is clear and bright, meeting the sensory quality requirements of tequila, without altering the original flavor.
• Material Requirements: Food-grade stainless steel, to prevent contamination of the liquor by the equipment material, prevent the release of metal ions, and comply with food contact safety standards, suitable for the production environment of alcoholic beverages.
• Core Requirements: The filtration precision must meet standards, effectively retaining fine sediment and powder activated carbon particles, ensuring the liquor is clear and free of impurities after filtration. The equipment must have good sealing performance to prevent liquor leakage and secondary contamination, be easy to operate, and convenient for daily cleaning and maintenance.

III. Equipment Selection and Customized Solution

Based on the customer’s needs, after on-site communication and process compatibility analysis, a 60L food-grade stainless steel plate and frame filter press was customized for the customer, specifically addressing the core pain points in tequila filtration. The core configuration and design of the solution are as follows:

1. Material Configuration: The entire machine is made of 304 food-grade stainless steel, including the filter plates, filter frames, feed ports, and discharge ports, all in compliance with food-grade safety standards, without any harmful impurities leaching out, completely avoiding the secondary pollution caused by traditional equipment materials, ensuring the food safety and quality stability of tequila, and meeting the requirements of food-grade production compliance.
2. Specification Adaptation: The effective volume of the equipment is precisely matched to 60L, with the single-batch filtration volume adjustable, suitable for the customer’s small-batch production mode, without occupying excessive workshop space, and easy to move, allowing flexible placement according to the production process, solving the problem of low filtration efficiency for small batches.
3. Filtration System Optimization: Equipped with high-precision food-grade filter cloth, the filtration precision can accurately retain powder activated carbon and fine sediment (particle size ≥ 1μm), using deep filtration principles, utilizing the multi-pore structure inside the filter cloth to gradually retain impurities. This not only achieves efficient solid-liquid separation but also avoids the rapid formation of a filter cake layer that increases filtration resistance, while maximizing the retention of the original flavor and nutritional components of tequila, without altering the sensory characteristics and quality of the liquor, meeting the core requirement of “removing impurities without altering the flavor” in tequila filtration.
4. Detail Adaptation Design: The equipment adopts a fully sealed structure to prevent liquor leakage and the entry of impurities from the air during filtration, ensuring the purity of the liquor; it is equipped with a convenient cleaning interface, allowing for quick cleaning of the filter cloth and filter frames after filtration, avoiding the clogging of the filter cloth by residual powder activated carbon, extending the service life of the filter cloth, and reducing manual maintenance costs; the operation panel is simple and easy to understand, with one-button start, no need for professional technicians, suitable for the daily operation needs of the customer’s workshop, reducing labor input.

IV. Equipment Application Effect and Customer Feedback

(I) Application Effect After the 60L food-grade stainless steel filter press was put into use, it perfectly matched the customer’s tequila filtration process, fully meeting the two-stage filtration requirements of “initial filtration after distillation and deep filtration before bottling” in the tequila brewing process. The specific application effects are as follows:

1. Retention effect meets the standards: Through the combination of high-precision filter cloth and deep filtration technology, it efficiently retains the sediment, powdered activated carbon and other tiny impurities in the tequila. The filtered tequila is clear and bright, with no visible impurities to the naked eye. After testing, the suspended solids content in the tequila has been reduced to meet the production standards of tequila, completely solving the problem of incomplete retention and turbidity of the tequila in the original filtration method, and meeting the normative requirements of tequila brewing in Mexico.
2. Food safety guarantee: The food-grade 304 stainless steel material is in full contact with the tequila throughout the process, without any metal ions leaching out. The equipment has passed food-grade safety tests and fully complies with relevant food production standards, effectively avoiding the risk of material contamination and ensuring the food safety of tequila, helping the customer smoothly pass relevant food certifications.
3. Flavor retention intact: The equipment adopts a low-pressure and stable filtration process, avoiding the damage to the flavor components of tequila caused by high-pressure filtration. The taste and aroma of the filtered tequila remain consistent with those before filtration, maximizing the retention of the unique flavor of tequila, meeting the quality positioning of the customer’s mid-to-high-end products, and conforming to the core requirement of “not changing the essence of the tequila” in the filtration process of tequila.
4. Convenient and efficient operation: The equipment is suitable for small-batch production. The filtration of 60L tequila per batch only takes 30-40 minutes, and the filtration efficiency meets the customer’s production schedule requirements. It is easy to clean, with a short single cleaning time, and no need to disassemble complex components, effectively reducing downtime for maintenance, reducing labor intensity, and improving production continuity.

(II) Customer Feedback
The customer highly recognizes the application effect of the 60L food-grade stainless steel filter press, with the core feedback as follows: ‘The equipment fully meets our tequila filtration needs. The 60L capacity is just right for our small-batch brewing mode. The operation is simple, and employees can quickly get the hang of it. The filtered tequila is clear and bright, with thorough retention of sediment and powdered activated carbon, and no damage to the original flavor of tequila. The food-grade stainless steel material also makes us more confident in food safety. The equipment operates stably and is easy to maintain, effectively solving the pain points in our previous filtration process, improving product quality and production efficiency. When we expand production in the future, we will continue to choose this model of equipment.’

V. Case Summary
