Consequently, although this material would eventually pass through the screen, the product would be ‘stirring’ rather than milling, taking an excessive amount of time, thereby producing a disproportionate amount of small particulate or fines. Scale-up and scale-down of chemical processes Special Topics in Industrial Chemistry Seppo Karrila November 2014 2. Scale-up from Laboratory to Pilot Plant UQUIFA has pilot plants al all three facilities in Spain and Mexico. Milling is the primary procedure used for size reduction of particles prior to tablet and capsule formation. Lab scale & Pilot scale & Large scale synthesis Dev-synthesis team is very well experienced in developing a scalable process starting from the lab scale batches. REMBE® is a safety specialist in explosion safety and pressure relief. This results in particles that are better size-distributed and higher quality. Overall, conical mills offer excellent scalability, producing predictable and comparable results as you progress towards larger batches. Spec Engineering offers custom engineering solutions, providing the latest technology to manufacturers in the food, beverage, plastics, and chemical industries. If there are large clumps in the bulk material that were absent in the laboratory testing (e.g. In this scale-up step, a system with a higher volume and a more complex equipment was used for co-digestion experiments (Fig. Importantly, this will also improve product solubility and bioavailability, ultimately delivering improved drug performance. For example, on a lab size machine ~50g of a 1kg batch may be retained in the screen under these conditions (5%). Hence, a significant role of lab milling is to provide a balance between a desirable particle and a realistically achievable process – a key deliverable should be handing over critical process parameters for the larger-scale pilot and production mills to follow. “Often, lab-scale scientists underestimate what their lab-scale work translates to in a pilot scale-up or a manufacturing process scale-up, in terms of matters associated with a purification workflow, for example,” says Xuemei He, senior process chromatography applications manager at Bio-Rad Laboratories. Starting point (1) is a lab protocol that is obtained from the lab experiments directly, a publication or a patent document. Nonetheless, planning for scale-up should begin before lab studies have even commenced. It is also imperative that teams engage in cross-departmental communication, to ensure lessons learned are carried forward to maximise the chance of scale-up success. Pilot Plant:- It is the part of the pharmaceutical industry where a lab scale formula is transformed into a viable product by development of liable and practical procedure of manufacture. Keep exploring the rest of the content on our site and check back often for more! Learn how your comment data is processed. We’re proud to be known for our expertise, quality products and tailor-made solutions. There are usually three steps in the process: lab milling, pilot milling, and production milling. Dec is a leading global provider of powder handling systems and process containment technologies. The plant-scale mill had four cages with different diameters and varying RPM. Getting that same result to scale-up seamlessly in the production stage is entirely different. Because you’re essentially multiplying your initial batch by 10 to get this larger scale, the size of your pilot (10x) laboratory batch will be: Keep in mind that while these numbers are standard, they are not a concrete rule. A good example may be the use of an HMI, which limits the operator to the simple execution of preset conditions, while affording the administrator a large degree of flexibility if required. due to compaction in storage), then the resulting particle size distribution of milled material may differ. Read our last “Size and Volume Reduction” e-newsletter campaigns here: Founded in 1987, Hanningfield Process Systems are experts in the design and manufacture of stainless steel process equipment for the pharmaceutical, food, chemical and allied industries. Transitioning from lab-scale chemistry to a pilot plant facility requires expertise in process modeling, process module design, system scale-up, power and controls integration and fabrication. In short, the pilot lab batch is the first replicated scale-up that you’ll create from the chosen formula. This should be regarded as a necessary evil; it is important to remember that the purpose of lab milling is to accurately forecast the outcome of a much larger production batch. Following the above guidelines will smooth and accelerate this path; ultimately this helps to achieve the original objective of delivering the necessary product specification, while satisfying the requirements of a highly regulated production environment. There are usually three steps in the process: lab milling, pilot milling, and production milling. Note that while there will be a more formal validation process that takes place later in the piloting sequence, process capability studies often occur during this second step of the pilot program. Eastern Instruments feeders allow for both accurate, real-time flow measurement, as well as very precise control of flow rate and total for nearly perfect batching or blending. At this time, the product will now be in its approved packaging, rather than standard packaging. Material is broken down into smaller, more consistent particles, which will be later blended, compressed and coated into the final dosage unit. These include screen type, impeller type, impeller speed and material pressure on the screen. For predominantly batch processes in which solids handling is not a major concern, scale-up from pilot scale directly to commercial scale may be possible. In most cases, the size of this initial (1x) laboratory batch will be: Before you can create tablet or capsule units, a process called milling must occur. This white paper will aim to help you scale-up with minimum disruption or deviation. At this stage, close liaison with the conical mill supplier is also recommended for drawing on process knowledge and understanding the capabilities and limitations of the machine prior to production commitments. Non-linear scale-up basically means you cannot take a chemical process in the lab and drop it into a pilot plant by simply increasing the chemicals and equipment involved in a proportionate manner. Scale up, Scale-up, or scaleup may refer to: Scalability, the ability to function with different amounts of required work, or to be readily adjusted to do so; Scale-up (chemical engineering) in chemical engineering, the migration of a process from the lab-scale to the pilot plant-scale or commercial scale; Scaleup company; See also In the case of a straight forward reaction (for eg. ATEX rated as standard. This stage can be completed as a joint effort between the development laboratories and manufacturing entities. Specifically, regularly used screens and impellers should be kept in stock for immediate replacement in case of loss, damage or wear. Upon successful completion of pilot production batches, the product will undergo additional stability testing in approved packaging. Microbial processes involve cultivation of microbes in bioreactors (also referred to as fermentors) to produce a product, as well as the subsequent recovery and purification of the product and disposal of associated wastes. Although throughputs vary with each individual application, a plausible example of batches through scale-up would be 1-10 kgs in the lab, 25-100 kgs in the pilot plant and 400-800 kgs in production. Plant:- It is a place were the 5 M’s like money, material, man, method and machine are brought together for the manufacturing of the products. For over 60 years we have provided protection solutions that can suppress, isolate and vent combustible dust or vapor explosions in process industries. In short, pilot scale up process describes the steps taken to develop a product before preparing the first pilot-production batch. In the Lab, we research the ‘Art of Scaling’ and translate our learnings into new knowledge and tools that support impact scale-ups. For material flow problems. Compared with hammer mills, conical mills will produce less fines to give a tighter PSD, be easier to clean and reassemble, and will produce less heat, noise and dust (many hammer mills require dedicated extraction). FAT, SAT, IQ, OQ, PQ).

No more banging! It might be unrealistic to assume that the scale-up process will work seamlessly and that products will perform as well in production as they did in the lab. Taking the validated scale-up procedure to the plant scale. In fact, there are a few factors that might control or alter the size of your laboratory pilot batch. Scale-up of straightforward reactions: Scale-up of some specialty chemical processes can directly benefit from using one of the 28 reactor systems in the Pilot Plant, ranging from 1 gal to 500 gal in scale as shown in Figure 2. Scale-up: from Kilo Lab to Pilot Plant During Process Development, thermal screening tools are used to identify thermal hazards, such as the onset of secondary reactions or decompositions of components in the reaction mix, should a thermal runaway of reaction occur.
