Diamond Series – Plate & Frame Filter Press

The Diamond Series plate and frame laboratory filter is designed for use in critical applications where hold-up volumes can be costly. Historically, plate and frame filter technology has required that upon completion of the production cycle, up to 90% of the liquid remaining in the filter needs to be reprocessed or discarded. The Diamond Series eliminates this obstacle entirely. Maximum yield of viable liquid is now possible.

Available in 4 inch, 8 inch, or 12 inch designs, Diamond Series  plate and frame laboratory filter is internally ported and eliminate the need for gaskets entirely.

The Diamond Series, in conjunction with ErtelAlsop’s patented BioClean Filter Plate technology, allows for effective cleaning and sterilization of every liquid contact surface. Our standard Validation Package, along with optional 20 Ra surface finish makes this the easiest filter in the world to validate.

What Are Some Plate & Frame Applications?

Small Batch Cosmetics

Depth filtration is necessary over a wide range of applications in the cosmetic and personal care industries. Cosmetic raw materials, ingredients and additives demand various degrees of filtration from clarifying filtration to final-polishing filtration prior to shipping.

These product applications include:

  • Esters
  • Botanical Extracts
  • Silicones
  • Essential Oils
  • Hydroalcoholic Fragrances and Colognes
  • Oleochemicals
  • Surfactants
  • Polymers
  • Other Specialty Ingredients

Depth filters play a major role in assuring the highest degree of quality for perfumes, colognes, lotions and creams.

The depth filtration process removes haze, salts, particulate, free water and possibly activated carbon and filter aids which were necessary additives for the refinement of the liquid cosmetic product. In some cases, decolorization is essential for the presentation of a clean, clear product. ErtelAlsopís Micro-Clear product line, with powdered activated carbon (PAC) integrated into the filter media, is the perfect solution for these filtration applications.

ErtelAlsop manufactures a wide range of cellulose based filter media for use with cosmetic and personal care products, which fit our wide selection of filtration equipment. Our filter media is tested and certified to meet organic standards and is free of GMOs, common Allergens, Phthalate and BPA.

Flavors & Fragrances

The filtration process for flavor and fragrance products is what achieves a high quality standard for clarity, color and stability.

Blends of aromatic organic compounds can be composed of natural, nature identical and/or synthetic ingredients. These are concentrated through distillation, mechanical separation, or extraction before finally going through the filtration process to clarify and polish the product before packaging.

The varying degrees of filtration demanded by flavors and fragrances are met by ErtelAlsop’s wide range of cellulose depth filter media and filtration equipment.

ErtelAlsop depth filters and media succeed in filtering diverse natural and synthetic flavor aroma chemicals, essential oils, oleoresins, distillates, extracts and liquid compounds to assure the highest degree of quality.

Depth Filtration in Flavor Applications

Flavor chemists formulate blends of materials to product extracts or liquid compounds. Depth filtration plays a critical role in the process to ensure the end product satisfies the customer.

Common applications include:

  • Particulate and Haze Reduction: ErtelAlsop Micro-Media depth filter media provides an ideal solution for reducing particulate loading in a wide variety of flavor products, effectively removing fine particulate that may collect over time at the bottom of product packaging.
  • Essential Oil Absorption: ErtelAlsop 100% Cellulose Alpha-Media filter media is used in flavor extract applications to absorb free oil remaining in the extract after it is chilled and decanted. The cellulose depth matrix provides simultaneous particulate and haze reduction.
  • Removal of insoluble waxes/lipids: Filtration ensures haze and wax residue will not be visible when the product is chilled or blended.
  • Removal of microbial contaminants: Finer grades of depth media can remove microbial contaminants as well as byproducts of fermentation processes.
  • Water Removal: Unwanted water contamination is sometime present in essential oils after extraction, either residual from the raw materials, or introduced in the manufacturing process. This water appears as a haze in the material, increasing the turbidity readings of the product. ErtelAlsop Zeta-Dri Pak Lenticular technology succeeds at removing water from essential oils during the filtration process. Both particulate and water can be removed in one pass through a Zeta-Dri Pak system.

Depth Filtration in Fragrance Applications

Expert perfumers in the fragrance industry draw from extensive palettes of essential oils and other fragrance materials. They scents they invent are enjoyed in a variety of products including fine fragrance, personal care, home care and home design products.

The filtration of essential oils for fragrances removes haze, particulate, and possibly filter aids which were used in the refinement of these liquids.

Common Applications Include:

  • Particulate and Haze Reduction: ErtelAlsop’s Micro-Media filter media provides a trusted solution to the varying degrees of filtration required by fragrance producers. The blending of essential oils with alcohols, water and other base solvents can result in the formation of additional haze or precipitates in the final product. Filtration of chilled fragrances through depth filter media is the quickest, most consistent and cost efficient means of polishing these liquids prior to filling.
  • Color correction: In some cases, color removal is essential for the presentation of a fragrance product. Micro-Clear filter media with activated carbon is the perfect solution for these filtration applications. The carbon impregnated filter media can be used in existing filtration equipment, removing the need to contaminate processing tanks with loose activated carbon. The process fluid can be recirculated through the filter media to achieve the required level of contact time with the activated carbon. Color correction and particulate removal can be achieved in one step.
  • Vapor Control: An ErtelAlsop Vapor Master Enclosed Plate and Frame Filter Press or Lenticular Housing allows for the both containment of vapors and the treatment of liquid with filter aids.

Diamond Series – 4D

The Model 4D is the smallest complete Plate and Frame Filter Press available today. It is the perfect tool for R&D, pilot, or small batch processing. The Diamond Series line offers one of the most revolutionary design innovations in the history of plate and frame filtration. By literally turning plate and frame filtration on its ear, ErtelAlsop has created a filter that provides complete drainage and venting while maintaining the superior internally ported design the company is famous for.

These filters are able to accept up to twenty (20) filter pads, and have excellent scale-up capabilities. The 4D has the same component flexibility as other models, accepts various thickness filter media, and is internally ported eliminating the need for gaskets as well as concerns about compatibility and cross-contamination.
