DESIGN AND DEVELOPMENT OF A PINEAPPLE ROLLED TART MAKING

MACHINE

By

PUA MING YEE

MAY 2011

Chairman: Rosnah Shamsuddin, PhD

Faculty: Engineering

Majority of pineapple rolled tarts are produced manually. Production is therefore slow

and supply is unable to meet the market demand. A rolled tart making machine is

essential for the efficient mass production of pineapple rolled tart. A machine that

would reduce processing time, labour, and operating cost and at the same time,

affordable for small-scale industries, was designed. Since food properties are varying

with time, prior to design processes, effect of dough and jam formulations on its

properties and kinetic studies of jam were studied. Effects of pineapple bakery jams

with different sugar compositions (0% to 33.3%) were evaluated at ambient temperature

based on total soluble solid (TSS), pH, viscosity, and moisture content. Simultaneously,

effects of different butter (23% to 45%), sugar (0% to 20%) and corn flour (0% to 15%)

compositions on hardness and stickiness of pineapple tart short dough were determined.

There were significantly increased (p< 0.05) in total soluble solids (TSS), viscosity, and

moisture content of jams at different sugar percentages, but no significant changes in

pH were observed. In textural analytical test, significant changes (p< 0.05) in hardness

and stickiness of pineapple tart short dough with different compositions of butter, sugar,

and corn flour were found. Cooking rate of pineapple bakery jam was investigated and

the effects of cooking temperature (70°C to 100°C), stirring speed (20 rpm to 100 rpm)

and batch volume (2 to 6 liters) on rate constant were examined. The linear relationship

between the logarithmic total soluble solids gain ratios of cooked jam and the cooking

time showed that the cooking rate followed the equation of first-order chemical reaction.

The cooking rates increased with cooking temperature and stirring speed, but decreased

with increasing batch volume. The activation energy of cooking process was 42.49

kJ/mol. Present investigation of cooking rate constant will be useful in designing more

efficient jam cookers with higher ratio of effective heating surface to batch volume of

fruit pulp.

Engineering design processes were carried out to develop the conceptual designs, which

were generated with Computer Aided Design (CAD) software and evaluated based on

customers’ requirements. The basic decision matrix was used as a decision making tool

for selecting the best design. The fabricated machine was tested at different screw

rotating speeds and dough formulations. The rolled tart throughput rates increased

significantly (p

mouth feel. The maximum and minimum rates for the standard dough formula were

4320 pieces per hour and 720 pieces per hour, respectively. The operating costs of

making tarts using the machine with the highest rate were reduced by 92.05%,

compared to the manual method. This machine achieved the objectives of research

which can produce tarts at high rate, low operating and labour costs and affordable for

small scale industries. This research provided the guideline how to manipulate the

dough and jam formulation, and simple way to determine the end point of jam cooking.

Fakulti: Kejuruteraan

Majoriti nanas tart gulung yang dihasilkan secara manual. Produktivitinya adalah sangat

rendah dan tidak dapat memenuhi permintaan pasaran. Sebuah mesin untuk membuat

tart gulung sangat penting dalam pengeluaran nanas tart gulung. Sebuah mesin

direkakan untuk mengurangkan masa pemprosesan, kos tenaga kerja dan kos operasi. Ia

juga sesuai untuk industri kecil. Sifat makanan adalah berbeza-beza dengan masa.

Sebelum proses rekabentuk dijalankan, kesan ramuan adunan dan jem ke atas sifatnya

dan kinetik masakan jem dikaji. Pengaruh komposisi gula (0%-33.3%) terhadap jem

nanas diuji pada suhu bilik berdasarkan jumlah pepejal terlarut (TSS), kepekatan, pH

dan kadar air. Secara bersamaan, kesan komposisi gula (0%-20% ), mentega (23%-45%)

dan tepung jagung (0%-15%) terhadap kekerasan dan kelekitan adunan ditentukan.

Terdapat perubahan yang signifikan (p

kelekitan adunan dijumpai dengan komposisi yang berbeza mentega, gula dan tepung

jagung. Kadar masakan jem nanas telah dikajikan dengan pengaruh suhu memasak

(70°C-100°C), kelajuan pengadukan (20rpm-100rpm) dan isipadu bac (2-6liter)

diperiksa. Hubungan linear antara logaritma jumlah pepejal nisbah dan masa memasak

menunjukkan bahawa tahap memasak mengikut persamaan reaksi kimia tertib pertama.

Kadar masakan jem meningkat dengan suhu dan kelajuan pengadukan, tapi menurun

dengan isipadu bac. Tenaga pengaktifan proses memasak adalah 42.49 kJ / mol.

Penyelidikan masakan jem berguna dalam mereka bentuk periuk yang memasak jem

dengen lebih efisien and efektif. Kejuruteraan proses rekaan dilakukan untuk

mengembangkan rekaan konseptual. Rekaan konseptual yang dihasilkan dengan

Computer Aided Design (CAD) perisian dan ia dinilai berdasarkan keperluan pelanggan.

Keputusan dasar matriks digunakan sebagai alat untuk memilih rekaan terbaik. Mesin

itu telah diuji pada kelajuan skru berputar dan formulasi adunan yang berbeza.
