New research brief: Dental stick extrusion utilizing spray dried plasma (SDP)

Study objetive   The study objective was to evaluate how SDP inclusion with other ingredients impacts texture of extruded dental formulas.   Experimental procedure   Three formulas were developed utilizing SDP to replace wheat starch (WS) or Arabic gum in the control formula. The formulas were: Control: WS and gum; SDP1: SDP and WS replacing gum; and SDP2: SDP replacing WS and gum. Dental sticks were made at the Extru-Tech technology testing center using a 525 single screw extruder with the product densification unit (PDU) removed and replaced with a mid-barrel valve and 3 cooling heads to cause densification. The sticks were manufactured as solid square sticks. Generally, a single screw with a PDU, or a traditional parallel-shaft twin screw is used to manufacture dental sticks. However, the equipment alterations used worked like a single screw with a PDU; thus, it would be expected that the results would translate to a traditional single screw configuration. Glycerin at 12% (% to dry feed rate) and chicken fat were added to the pre-conditioner at set rates to optimize expansion and product quality. Processing conditions were monitored and adjusted on the various formulations during production to optimize extrusion. Texture was measured on a TA.XT Plus utilizing an adjustable bridge with a rounded-end knife probe for a 3-point bend. Dental sticks of 8 cm in length were placed over the two bridge spans spaced 5 cm apart to measure maximum force (hardness) and work to peak force (work to break) to determine texture parameters. Ten dental sticks per treatment were analyzed.   Treatments     Dental stick run conditions     Results and discussion     Summary   In conclusion, SDP can be incorporated into dental stick formulas and utilized as a processing aide. Overall, depending on target hardness and ingredient matrix, SDP can be an alternative to various ingredients to maintain or improve product quality.    Source: APC

Recovery of by-products in the manufacture of pet food

Challenges with wet by-products   Wet by-products have a high moisture content, making them difficult to handle due to their rapid decomposition and the generation of unwanted microorganisms that can put pet health at risk. Generally, these by-products are marketed at low value for feed farm animals or are discarded.   Problems with process fines   Fines are often reinserted inefficiently into the grinding or mixing process, leading to several problems: Grind a product that has already been ground Consume additional energy in grinding Wear on hammers and mill sieves Affect the capacity of the equipment that reprocesses these by-products   Sustainable solution: By-product Recovery System (SRS)   The By-product Recovery System (SRS) is a proven solution to reduce, reuse and recycle both wet and dry by-products, regardless of size, temperature and moisture content.
  SRS components   The SRS has two tanks: Homogenization tank: receives the by-products to be recovered. It has a specially designed blade that rotates at high speed to achieve a homogeneous mixture (slurry) with an approximate concentration of 20% by-products and 80% water at a temperature between 40 and 50 °C. Maintenance tank: once the homogeneous mixture is achieved, it is transferred to this tank through pipes. Here, a mixer keeps the slurry homogeneous and at the proper viscosity.   The SRS control system communicates with the preconditioner-extruder PLC to ensure the correct water content within the preconditioner and extruder, avoiding unwanted variations in moisture content and guaranteeing optimal quality and uniformity of the final product.
  Advantages of SRS   Recovery of investment in a short time Immediate use of all by-products, avoiding the generation of unwanted microorganisms Optimization of process times Decrease in labour requirements Improved traceability Achievement of automation Compliance with FDA and EHEDG certifications Made of stainless steel Adaptable to plant spaces through horizontal or vertical layout   SRS sizing   To size the appropriate SRS for your process, it is necessary to determine the number of by-products generated. With this information, the appropriate model can be selected. There are three standard models: SRS150, SRS300 and SRS600, which recover 150, 300 and 600 kg/h respectively. Special solutions can also be designed according to specific needs.   By: Clivio Solutions   Source: All Pet Food Magazine

CPM IDAH presents the TwinTech extruder for the Pet Food and Aqua Feed market

In March, CPM IDAH presented the clearest evidence of that collaboration at the Victam Asia 2024 show: the new TwinTech twin-corotative screw extruder. This TwinTech extruder updates IDAH's well-known twin-screw extruder with innovations and design techniques from CPM Ruiya Extrusion, along with the long-lasting gearbox and energy-efficient motor from the renowned CPM equipment.   Collaborative development   "This extruder is the result of collaboration between the CPM brands IDAH (Taiwan) and Ruiya Extrusion (China)," says Ezequiel Villar, Business Development Manager for Latin America at CPM IDAH. "We combined their knowledge of design, robustness, and profitability with our knowledge of food production to introduce a new technology."   The CPM gearbox and motor also offer real advantages in the TwinTech. 'The gearbox allows rotational speeds of up to 600 RPM, making it easier to process heavy loads and increase performance, along with a proven long service life,' says EV. TwinTech's CPM motor is a permanent magnet synchronous motor (PMSM), which offers significant advantages: "The CPM motor requires less energy," says EV. "It also reduces size and noise emission by approximately 30%." Combined, these innovations create a market-leading twin-screw extruder that delivers capacity, value, and reliability.   TwinTech details   The TwinTech extruder offers a range of new features developed by both IDAH and partner brands within CPM: Improved Gearbox technology: Powered by CPM's renowned and proven gearbox technology, the TwinTech extruder features a high-speed, heavy-duty gearbox capable of a rotational speed of up to 600 RPM. This allows for increased processing capacity and efficiency. Energy efficient design: The TwinTech extruder is powered by a permanent magnet synchronous motor (PMSM), which is highly efficient and approximately 50% smaller than traditional air-cooled motors. This motor design contributes to energy savings, reduced noise pollution (up to 30% less), and the option of water cooling to maintain the motor. Density control unit: An optional feature, the density control unit, allows TwinTech to produce different food types using the pressure inside the cutting chamber. This versatility allows manufacturers to produce a wide range of feeds with a single machine. Advanced preconditioning and cooking systems: These systems are designed to improve the cooking process by ensuring effective steam integration and retention, resulting in greater processing efficiency and product quality.   Our CPM IDAH TwinTech extruder is a guaranteed solution to increase product quality levels with lower energy and wear costs. Regionally, we see an increase in consumption and specific growth in premium food by users, which generates the responsibility of the entire chain to have efficient solutions given the limitations that our clients face with the increase in ingredient, energy, and overhead costs. But despite these challenges, high-quality products are still expected to be supplied to a very competitive market. The TwinTech extruder is a cutting-edge solution that combines the experience of IDAH and the technology and robustness of CPM, offering the pet food industry a reliable and efficient tool.   By: CPM IDAH Source: All Pet Food Magazine
