PERALATAN PENCAMPURAN (MIXING EQUIPMENT) Dr. Ir. Meika Syahbana Rusli, MSc

Tujuan Pencampuran: Bergabungnya bahan menjadi suatu campuran yang sedapat mungkin memiliki kesamaan penyebaran yang sempurna Jenis agregat komponen dalam suatu campuran : 1. Campuran gas ; 1. Contoh : udara 2. Campuran bahan cair; 1. Contoh : larutan, emulsi 3. Campuran bahan padat-bahan cair; 1. Contoh : suspensi, pasta 4. Campuran bahan cair-gas; Contoh : minuman yang mengandung CO 2

5. Campuran bahan padat; Contoh : pakan ternak, adukan semen pasir 6. Campuran gas-bahan padat; Contoh : asap • Homogenisasi campuran jenis 1 dan 6 dilakukan dengan bantuan aliran turbulen melalui pompa • Homogenisasi campuran jenis 2 s/d 5 dilakukan melalui : v A. pengadukan v B. pencampuran bahan viskous v C. pencampuran bahan padat

Pengadukan bahan cair Tujuan : a. Mensuspensikan bahan/partikel padat b. Menggabungkan bahan-bahan cair yang dapat saling bercampur c. Mendispersikan gas dalam bentuk gelembung gas halus d. Mendispersikan bahan cair lain yang tidak dapat bercampur e. Meningkatkan pindah panas antara bahan cair dan penukar panas Dalam suatu proses pengadukan, beberapa tujuan tersebut diatas dicapai secara sekaligus. Contoh : proses hidrogenasi katalitis minyak nabati

Rancangan alat pengauk (agitators) Secara umum agitator terdiri dari : 1. bejana (vessel) 2. sumbu berputar (As) 3. pengaduk (impeller) 4. penggerak (motor) 5. pemecah aliran (buffle)

Lee Agitators All Lee agitators feature a unique offset frame construction which brings the points of the scrapers to the centerline, thus insuring uniform scraping action throughout the entire processing cycle. Lee agitators also offer sanitary advantages and an opportunity to reduce operating costs as they do not have to be removed and broken down for cleaning. Lee agitators are available in various standard styles and sizes, also.

Other features include: Exclusive centerline scraper assembly assures uniform scraping and complete mixing. Scrapers are hinged to the frame above and back of the center at a steep pitch, thus moving the heated film of the product continuously toward the center of the kettle. Option of fixed or variable speed, electric or hydraulic motors. Agitator drive mounted in a heavy stainless steel channel with special lip seal to prevent leakage into product. Choice of hydraulic cylinders for easy tilt-out of agitator. USDA approved scraper blades available in a choice of quality materials, including: molded nylon, nickel alloy castings, and Teflon. Fully-enclosed gear box with heavy-duty gears assures reliability and long life. Lee assembles, tests and runs all agitator assemblies before shipment. Standard agitator is supplied with a USDA approved bottom support bushing. All scraped-surface agitators can be installed at an incline in hemispherical bottom vessels.

Pressurized and sealing mixing chamber to provide high mixing performance and prevented environmental pollution. 5. Easy to installation, operation and maintenance to lower the running cost.

SIGMA KNEADER

Excellent for kneading and mixing of highly viscous materials like dough, putty, rubber solutions, adhesives, polymers etc. The mixing action is a combination of smearing, stretching, folding, dividing and recombining as the material is processed between the sigma blades and the container walls. Jacket arrangement is provided for heating or cooling application. In bigger models the container is tilted by a hydraulic cylinder to ensure complete discharge of mass.

MIXER TIPE V

General This Mixer is applicable for mixing powdery or granular materials in pharmaceutical and other industries. It consists of two V-Type cylinders of different altitudes, and through mechanical transmission, the materials in these cylinders are made to move back and forth and turn over again and again, thereby achieving the goal of uniform mixing. This Mixer has the following distinguishing features, no blind angle in the cylinders, no accumulation of materials, high speed, and short mixing time. With the body made of stainless steel and both inner and outer walls polished, the cylinders have elegant appearance the charging of materials can be made either by manual operation or through vacuum suction. For discharging, rotating valves and rapid swivel heads are adopted.
